Answer:
60
Step-by-step explanation:
did this before so easy
H = V/B

The base of the prism is given by the expression 2X^2+8x-9
then c)5x+3
Answer:
x = 2.5 inches. Or
x = 5/2
Step-by-step explanation:
Length: 7 + 2x
Width: 5 + 2x
Note that you have to add x at each end of the picture and onto each part of the width.
The entire area is 120 square inches.
Formula
L*W = Area
(2x + 7)(2x + 5) = 120
Solution
4x^2 + 10x + 14x + 35 = 120 Subtract 120 from both sides. Add xs
4x^2 + 24x + 35 - 120 = 0
4x^2 + 24x - 85 = 0 Factor
(2x + 17)(2x - 5)
2x + 17 has no meaning. It will give - 8.5 which is not possible.
2x - 5 =0
2x = 5 Divide by 2
x = 5/2
x = 2.5
Note: I don't know which one the computer is looking for.
3/4 is 1/3 of what number?
For this problem we just need to do the following division:

And we can solve for the value of x desired and we got multiplying both sides by 3:

So then we can conclude that 3/4 is 1/3 of 9/4
Answer: 9/4
Expression:
Answer:
yes because 1/2= .5
and 6/12= .5 so they are equivalent
