Jessica’s mistake is that when isolating h from b, she multiplied b instead of dividing it on both sides. The new formula for h would be A/2b=h.
Now let’s solve. 23/2(6)=h
23/12
Approx. 1.91

Step-by-step explanation:
Cora is making a rectangular prism. She plans to have 8 inches if height. What will be the volume of the rectangular figure?
As the figure formed is a rectangular prism. we need to find the volume of rectangular prism. Volume of prism will be:
Volume = Length · Width · Height
As she wants to have 8 inches of height, substitute it in the given equation:
Volume = 8(Length · Heights) inch³
Y = 11.5x + 22
y = -13x + 218
when will their balance be the same.....ur basically just subbing in 1 y for the other and u get :
11.5x + 22 = -13x + 218....now we solve for x
11.5x + 13x = 218 - 22
24.5x = 196
x = 196 / 24.5
x = 8 <== they will be the same at 8 weeks
11.5(8) + 22 = 114
-13(8) + 218 = 114
and they will both have $ 114 at 8 weeks <===
Using Pythagorean theorem
x^2 + 6^2 = sqrt(117)^2
x^2 + 36 = 117
x^2 = 117 -36
x^2 = 81
x = sqrt(81)
x = 9
