The given triangle is a right triangle as shown by the square symbol inside. With this, we can solve the length "x" of this triangle using the Pythagorean Theorem.
[tex]c^2=a^2+b^2[/tex]where c = length of the hypotenuse and "a" and "b" are any of the remaining sides.
In our triangle, we have 7 as our hypotenuse and 2 as the length of the one side. Let's apply these values in the formula above.
[tex]\begin{gathered} 7^2=2^2+b^2 \\ 49=4+b^2 \\ 49-4=4+b^2-4 \\ 45=b^2 \\ \sqrt[]{45}=\sqrt[]{b^2} \\ \sqrt[]{45}=b \\ 3\sqrt[]{5}=b \end{gathered}[/tex]Therefore, the value of x is √45.

Answer:
The height of the triangle is 3 inches.
Explanation:
Given:
[tex]\begin{gathered} \text{Base of the triangle}=3\frac{2}{5}\text{ inches} \\ \text{Area of the triangle}=5\frac{1}{10}\text{ inches} \end{gathered}[/tex]We change the mixed fractions to improper fractions below:
[tex]\begin{gathered} \text{Base of the triangle}=3\frac{2}{5}=\frac{(5\times3)+2}{5}=\frac{17}{5}\text{ inches} \\ \text{Area of the triangle}=5\frac{1}{10}=\frac{(10\times5)+1}{10}=\frac{51}{10}\text{ inches} \end{gathered}[/tex]We want to find the height of the triangle.
Recall that the area of a triangle is calculated using the formula below.
[tex]\text{Area}=\frac{1}{2}\times\text{Base}\times Height[/tex]Substitute the given values:
[tex]\frac{51}{10}=\frac{1}{2}\times\frac{17}{5}\times\text{Height}[/tex]Multiply the numerators and denominators on the right side of the equation.
[tex]\begin{gathered} \frac{51}{10}=\frac{1\times17}{2\times5}\times\text{Height} \\ \frac{51}{10}=\frac{17\times\text{Height}}{10} \end{gathered}[/tex]Multiply both sides by 10.
[tex]\begin{gathered} \frac{51}{10}\times10=\frac{17\times\text{Height}}{10}\times10 \\ \implies51=17\times\text{Height} \end{gathered}[/tex]To solve for the height, divide both sides by 17.
[tex]\begin{gathered} \frac{51}{17}=\frac{17\times\text{Height}}{17} \\ 3=\text{Height} \\ \text{Height = 3 inches} \end{gathered}[/tex]The height of the triangle is 3 inches.
The distance-time graphs below represent the motion of a car. Match the descriptions with the graphs. Explain your answers
5. the car is stopped
6.the car is traveling at a constant speed
7. the speed of the car is decreasing
8. The car is coming back
The given speed time graphs represents the outline of the speed of the car with time.
The correct options are;
Graph E matches the description of the car is stopped, because it consists of an horizontal line at a pro on the x–axis
Graph F matches the description the speed of the car is decreasing because graph E is a straight line graph that slopes downward from left to right
Graph G matches the description, The car is traveling at a constant speed because the graph remains the same as the time increases
Graph H matches the description of the car the car stoped because the location of the graph is on the x-axis
Graph F represent matches the description of the car speeding up
What is a speed time graph?A speed time graph is one that shows the variation of speed with time for an object.
The given graphs in the question are speed time graphs such that we have;
5. When the car stops, the speed is zero, and the graph consists of an horizontal line (showing that the zero speed (stopping) is constant over a period of time) that is located on the x–axis, where the y–axis value is zero.
Graph H matches the description of the car is stopped because the graph consists of an horizontal line located on the x–axis
Graph
6. When the car is in motion, and the speed is constant, the graph will consist of an horizontal line at the specified speed. The horizontal line at the speed indicates that the speed is not changing.
Graph G matches the description of the car is traveling at a constant speed because the graph consists of a horizontal line at a positive y–value larger than zero or above the x–axis
7. When the speed of the car is decreasing, it means that as the time increases from left to right, the speed is decreasing simultaneously, which is given by a graph of a straight line that slopes downward as the time increases from left to right
Graph E matches the description of the speed of the car is decreasing because the graph consists of a straight line graph that slopes from left to right.
8. The graph of a car coming back is given by a graph that has negative y–values, such that the line of the graph is in Quadrant IV

--Multiplying Polynomials--Use the given formulas to express the volume of each object as a polynomial.
32.
V = L*w*h
Where:
V= Volume
L= Length = x+5
w= width = x-2
h= height = 6
Replacing with the values given:
V= (x+5) * (x-2) * 6
V =[ (x*x) + (x*-2) + (5*X) +5*-2) ] * 6
V= [ x^2 - 2x + 5x - 10 ] * 6
V= [ x^2 + 3x - 10] *6
V= (x^2*6) + (3x*6)+ ( - 10 * 6)

I don’t know what the first step is to solve this problem, so I need help :)
We have to find the first step to solve the equality:
[tex]\frac{2x-5}{2}=-18[/tex]As the quotient is blocking us from substracting an adding to solve the equation, the first step is to remove the denominator by multiplying both sides by 2.
Then we would get:
[tex]\begin{gathered} \frac{2x-5}{2}\cdot2=-18\cdot2 \\ 2x-5=-36 \end{gathered}[/tex]And we can continue to solve the equality.
Answer: Option B. Multiply by 2 on both sides.
Solve the following using substitution: 3X = 6Y -44X + 3Y = -1
We need to solve the system:
[tex]\begin{gathered} 3x=6y-4 \\ 4x+3y=-1 \end{gathered}[/tex]The first step is to isolate one of the variables and replace it at the other equation. We will isolate the "x" variable on the first equation:
[tex]x=\frac{6y}{3}-\frac{4}{3}[/tex]Then we replace this value on the second equation:
[tex]\begin{gathered} 4\cdot(\frac{6y}{3}-\frac{4}{3})+3y=-1 \\ \frac{24y}{3}-\frac{16}{3}+3y=-1 \\ \frac{24y-16+9y}{3}=-1 \\ 33y-16=-3 \\ 33y=-3+16 \\ 33y=13 \\ y=\frac{13}{33} \end{gathered}[/tex]We can use this value to determine x.
[tex]\begin{gathered} x=\frac{6\cdot\frac{13}{33}}{3}-\frac{4}{3} \\ x=\frac{\frac{78-132}{33}}{3}=\frac{\frac{-54}{33}}{3}=\frac{-54}{99}=\frac{-18}{33}=\frac{-6}{11} \end{gathered}[/tex]The solution to the system is (-6/11, 13/33)
write the equation y-4=1/3(x+6) in slope intercept form.
Given the equation:
[tex]y-4=\frac{1}{3}(x+6)[/tex]to write it in slope intercepept form, we have to solve for y the expression.
In this case, we have the following:
[tex]\begin{gathered} y-4=\frac{1}{3}(x+6)=\frac{1}{3}x+\frac{6}{3}=\frac{1}{3}x+2 \\ \Rightarrow y=\frac{1}{3}x+2+4=\frac{1}{3}x+6 \\ y=\frac{1}{3}x+6 \end{gathered}[/tex]thus, the equation in slope intercept form i s y = 1/3x+6

Clues to recognize the graph:
-The graph will cross from the first quadrant into the third quadrant.
-The graphs of cubed equations are looking like an S shape.
-The graph must cross at y = 1 because when x is zero y is 1
If x=0 in our equation y= x^3 + x^2 + x + 1 will be y=1
-The graph must have a zero at x= -1 because if we rewrite the equation
y= x^3 + x^2 + x + 1 = (x+1)(x²+1) and here we see that one of the roots or zeros is (x+1) = 0, x= -1
