Given sides of the triangle:
3x^2 + 8,2x^2 + x, andx - 3.We know that the perimeter of a triangle is the sum of all the sides of a triangle.
Perimeter of the triangle,
= 3x^2 + 8 + 2x^2 + x + x - 3
= 3x^2 + 2x^2 + x + x + 8 - 3
= 5x^2 + 2x + 5
Therefore, the perimeter of the triangle is 5x^2 + 2x + 5. Hence, the option A is the correct answer.
Solve for v in terms of s, t, and u.
S = U-t + V
V = what??
Answer:
[tex]v=s-u+t[/tex]
Step-by-step explanation:
Hi there!
[tex]s=u-t+v[/tex]
Our goal is to isolate v on one side of the equal sign.
Subtract u from both sides:
[tex]s-u=u-t+v-u\\s-u=-t+v[/tex]
Add t to both sides to isolate v:
[tex]s-u+t=-t+v+t\\s-u+t=v\\v=s-u+t[/tex]

Accuracy is how _______ a measurement is to the expected value'
Answer:
Accuracy is how close a measured value is to an accepted value. Precision is how close measurements are to one another. To make measurements, you have to evaluate both the accuracy and the precision to get a correct value.

what number can go into 2470,121 and 45
Answer:
Step-by-step explanation:
All of these numbers can be divided by 2, 3, 5, 7, 11, 13...
There is no whole number if you want to divide each number.
121 only goes into 1, 11, and 121. No other numbers have 11
45/2 = 22.5
45/3 = 15
45/5 = 9
2470/2 = 1235
2470/3 = 823.33333...
2470/5 = 494

Cameron has a bag that contains one silver (S) and one gold (G) marble. The marbles are the same size. Cameron chooses one marble at random and then puts it back in the bag. Then he chooses a second marble. The outcome "GS" means that a gold marble was chosen first and a silver marble was chosen second.
Answer:
(SS,SG,GS,GG) Probability 0.25
Step-by-step explanation:
i don't know how to do this
Heyo!
So, first things first:
Based on the data shown, it appears that Cameron has 1/4 a chance to really recieve any combo of the following. Hence, he can get SS, SG, 6S, GG. So, each chance he picks, he has a 0.25 chance of probably recieving any of the combo. So, the outcome order is (SS, SG, GS, GG) and the probability for each is 0.25.
It hard to really describe how to write it out without an image, but I hope this helps! Pls, lmk if it does! Good luck!

if a + b + c is cast 20 and a + b is equal to 14 , then c is what by process
Answer:
6
Step-by-step explanation:
[tex]a + b + c = 20[/tex]
[tex]a + b = 14(i)[/tex]
Putting value (a + b) in the above equation
[tex]14 + c = 20[/tex]
[tex]c = 20 - 14[/tex]
[tex]c = 6[/tex]
Another strategy for graphing a piecewise function is to use a table of values. The table below has a column for the input values x and for each piece of the function. The shaded cells indicate where the pieces do not define the function for those input values and so you do not need to find those values. You will need to decide which piece is used to define the function when x=3
Answer:
Step-by-step explanation:
Q&A. Can more than one formula from a piecewise function be applied to a value in the domain? No. Each value corresponds to one equation in a piecewise formula.

D. 2⁴(3 x 5⁵ + 2¹⁶)
Plz help meee!
Answer:
B. 2³(3 x 5² + 2²)
Step-by-step explanation:
2³(3 x 5² + 2²)
Step 1. Simplify the exponents
8(3 x 25 + 4)
Step 2. Multiply 3 and 25
8(75 + 4)
Step 3. Add 75 and 4
8(79)
Step 4. Multiply

Answer:
Option B. 2³(3 x 5² + 2²) is correct
Step-by-step explanation:
2³(3 x 5² + 2²)
First of all multiply the exponents
8×(3×25+4)
Then do the multiplication of 3 and 25
8×(75+4)
Now add the following numbers in the bracket
8×(79)
And the last multiply the following numbers
8×79
632
[Hence, the expression 2³(3 x 5² + 2²) is equal to 632. ]
Three liquids are to be mixed in the ratio of 5:3:1 . If ten liters is to be produced, how much of each of the ingredients should be used ?
Answer:
4,320
Step-by-step explanation:
One gallon = 15,140 drips
One liter = 4,000 drips
The ingredients that should be used will be ( 50 / 9 ), ( 5 / 3 ), and ( 10 / 9 ).
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that three liquids are to be mixed in the ratio of 5:3:1.and their total is ten liters. The quantity of each part will be calculated as:-
Let the ratio is L₁ = 5x, L₂ = 3x and L₃ = x.
5x + 3x + x = 10
9x = 10
x = 10 / 9
The fraction of each part will be calculated as:-
5x = 5 x { 10 / 9 ) = 50 / 9
3x = 3 x ( 10 / 9 ) = 10 / 3
x = 10 / 9
Therefore, the ingredients that should be used will be ( 50 / 9 ), ( 5 / 3 ), and ( 10 / 9 ).

Find the equation of this line. y= [?]x+[?]
Answer:
[tex]y=3x-4[/tex]
Step-by-step explanation:
Hi there!
Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x=0)
1) Determine the slope (m)
[tex]m=\displaystyle\frac{y_2-y_1}{x_2-x_1}[/tex] where two points that fall on the line are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
On the graph, two points are highlighted for us: (0,-4) and (2,2). Plug these into the formula:
[tex]m=\displaystyle\frac{2-(-4)}{2-0}\\\\m=\displaystyle\frac{2+4}{2}\\\\m=\displaystyle\frac{6}{2}\\\\m=3[/tex]
Therefore, the slope of the line is 3. Plug this into [tex]y=mx+b[/tex]:
[tex]y=3x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=3x+b[/tex]
Recall that the y-intercept occurs when x=0. Given the point (0,-4), the y-intercept is therefore -4. Plug this into [tex]y=3x+b[/tex]:
[tex]y=3x+(-4)\\y=3x-4[/tex]

The Piersons have paid $75 to enroll their son Fred at preschool. They will pay $152 a month in fees. Write and solve an equation to work out how many months it will take for the total bill to reach $683.
Answer: 4 months
Step-by-step explanation:
$75 + $152X = 683
That's the equation you need to set up, with X being the number of months.
To solve, first subtract 75 from both sides.
$152x = 608
Then, divide each side by 152
X = 4
The answer is 4 months.

For what values of x is the equation X^2-x=20 true?
Answer: x = 5 or x = -4
Step-by-step explanation:
Given equation
x² - x = 20

x² - x - 20 = 0
Cross factorize the equation
x -5
x 4
Factorize the equation
(x - 5) (x + 4) = 0
