The answer would be A.
If you fill in x for both you would get
y = (3 * 3) - 5
y = 4
y = (4 * 3) - 8
y = 4

If a and b represent the height and base of the triangular face, and h represents the length of its hypotenuse, and w represents the width or thickness of the prism, the surface area (A) is
.. A = ab +w*(a +b+ h)
Of course the area of each triangle is (1/2)ab, but there are two of them, so their total area is ab.
Put in the numbers and do the arithmetic. If you have a lot of them all specified in this way, a spreadsheet can make short work of it.
A = 5*12 +4*(5 +12 +13) = 160 . . . square inches
$21.30. You just have to add the numbers together.
Hello!
Judging by the question you have provided I have come up with an equation to find the answer!
The equation is as follows: $0.25(Amount of quarters)(40) + $0.10 (Amount of dimes)(50) + $0.05 (Amount of nickels)(40) = Total Money!
First you want to input the amount of each coin(s) that you have.
Your new equation should be
$0.25 (4)(40) + $0.10 (3)(50) + $0.05 (6)(40).
If you solve the equation you should get $67.00 as your total!
Hope this helped!
