Choose the correct expanded form for the following expression .
Evaluate 7/8^2
The correct expanded form for the following expression is 7/8 × 7/8.
What is expanded form?The division of numbers into their component ones, tens, hundreds, thousands, ten thousand, and so forth creates the expanded form of the number. The expanded version of the number is the sum of each digit times its place value, which is used to represent the number. A number is broken down to show the value of each of its digits in order to be written in expanded form. 144 would then be converted to 100 + 40 + 4 = 144. It can be used to compute sums as well. When a number is expanded to show the value of each digit, it is written in expanded form. The numerical value of each digit in the number we are writing is represented using extended form.

A rectangular carport has area 150 square feet. The height of the carport is five feet less than twice its length. Find the height and the length of the carport.
We are given that the area of a rectangle is 150 square feet. If "h" is the height and "l" is the length then the area is given by:
[tex]hl=150[/tex]We are also given that the height is 5 feet less than twice its length, this can be written mathematically as:
[tex]h=2l-5[/tex]Now we can replace the value of "h" in the equation for the area:
[tex](2l-5)l=150[/tex]Now we use the distributive property:
[tex]2l^2-5l=150[/tex]Now we have a quadratic equation that can be written as:
[tex]2l^2-5l-150=0[/tex]We can factor this equation to determine the values of "l". We multiply and divide by 2:
[tex]\frac{4l^2-5(2l)-300}{2}=0[/tex]Factoring in the numerator:
[tex]\frac{(2l-20)(2l+15)}{2}=0[/tex]Now we take common factor in the first parenthesis in the numerator:
[tex]\frac{2(l-10)(2l+15)}{2}=0[/tex]Simplifying:
[tex](l-10)(2l+15)=0[/tex]Now we set each factor to zero:
[tex]\begin{gathered} l_1-10=0 \\ l_1=10 \\ 2l_2+15=0 \\ l_2=-\frac{15}{2} \end{gathered}[/tex]We take the positive value, therefore, the length of the rectangle is 10 feet. Now we replace this value in the equation for the height.
[tex]h=2(10)-5[/tex]Solving we get:
[tex]\begin{gathered} h=20-5 \\ h=15 \end{gathered}[/tex]Therefore, the height of the rectangle is 15 feet.

In a rectangle the base measures (x + 7), height (x + 2), area = 36 cm
Calculate perimeter, height and base.
The values are given as;
Perimeter = 26cm
Height = 4cm
Base = 9cm
How to determine the valueThe formula for determining the area of a rectangle is expressed as;
Area = lw
Where;
l is the length of the rectanglew is the width of the rectangleNow, substitute the values into the formula, we have;
36 = (x +7)(x + 2)
Now, expand the bracket
36 = x^2 + 2x + 7x + 14
collect like terms
36 = x^2 + 9x + 14
Make into quadratic equation
x^2 + 9x + 14 -36 = 0
x^2 + 9x - 22 = 0
Factorize the equation
x^2 + 11x - 2x - 22 = 0
Factorize further
x(x + 11) - 2( x + 11) = 0
Then, x - 2 = 0, x = 2
or x + 11 = 0
x = -11
Height = x + 2 = 4cm
Base = x + 7 = 9cm
The formula for perimeter is expressed as;
Perimeter = 2( l +w )
Perimeter = 2( 4 + 9)
Perimeter = 2(13)
Perimeter = 26 cm
Hence, the values are 26cm, 4cm and 9cm respectively.

GIVEN
1) Females outnumber males by 3 to 2.
2) There are 1770 people in the city.
SOLUTION
Let the number of males be x and the number of females y. Therefore, the total number of people can be written to be:
[tex]x+y=1770\text{ -----------(1)}[/tex]If there are 3 females for every 2 males, we have that:
[tex]\begin{gathered} \frac{y}{3}=\frac{x}{2} \\ \therefore \\ x=\frac{2y}{3}\text{ ----------(2)} \end{gathered}[/tex]We can substitute equation (2) into equation (1) and solve for y:

3) Triangle ABC is dilated by a scale factor of 4 to form triangle A'B'C'. Wha-are the coordinates of vertex A'? Make sure that you enter the coordinatesin the form of (x, y) below. *Your answer
Answer
A' (-8, 4)
Explanation
When a figure, that is on the coordinates system is dilated (that is, enlarged or reduced) with respect to the origin, the new coordinates of its edges is simply a product of its old coordinates and the scale factor.
For this question, the coordinates of A is (-2, 1) and the dilation of the triangle ABC is by a scale factor of 4.
So, the new coordinates of A will be calculated thus
A (x, y) = A' (x × scale factor, y × scale factor)
A (-2, 1) = A' (-2 × 4, 1 × 4) = A' (-8, 4)

a rectangles width is 11 feet more than its length if the perimeter is 54 feet what is the length and width?
Let the length of the rectangle be l and the width be w
width is 11 feet more than length: we can write:
w = 11 + l
Also , perimeter is 54, we can write:
2l + 2w = 54
Note: Perimeter is sum of all sides
Now,
we replace 1st equation in 2nd and find l:
[tex]\begin{gathered} 2l+2w=54 \\ 2l+2(11+l)=54 \\ 2l+22+2l=54 \\ 4l=54-22 \\ 4l=32 \\ l=\frac{32}{4} \\ l=8 \end{gathered}[/tex]w is 11 + l
So,
width is 11 + 8 = 19
Length = 8 feet
Width = 19 feet

The correct answer is
[tex](\frac{f}{g})(x)=-x^2+x-1[/tex]To solve this, first let's write the division:
[tex]f(x)=x^4-x^3+x^2,g(x)=-x^2\Rightarrow(\frac{f}{g})(x)=\frac{x^4-x^3+x^2}{-x^2}[/tex]Now we can factor out a x^2 on the top and the bottom of the expression:
[tex](\frac{f}{g})(x)=\frac{x^4-x^3+x^2}{-x^2}\Rightarrow(\frac{f}{g})(x)=\frac{x^2(x^2-x+1)}{x^2(-1)}[/tex]Now we can cancel out and divide by (-1), or the same thing, multiply by (-1):

Solution
The slope of a straight line can be found from any graph by first drawing a triangle against the straight line indicating the rise and the run
The triangle usually is gotten by drawing straight lines from points on the graph where the line passes exactly across the intersection of lines of the y-axis and the x-axis
The circled points are good for usage to get the slope because the line passes exactly at the intersection of the vertical and horizontal line of the graph
Below is how the triangle will look
