Answer:

Step-by-step explanation:

Add
to both sides

Divide both sides by 11

So the surface area of a box has this equation: A = 2 (wl + hl + hw)
w = width = 38
l = length = 38
h = height = 0.25
Plugging in:
A = 2 ((38*38) + (38*0.25) + (38*0.25))
= 2926 square meters
Answer:
B
Step-by-step explanation:
If the diameter of sphere B is 42, that means the radius is half, so it is 21.
The question is asking what multiplied by 24 is 21, or 21 divided by 24. 21/24 can be simplified to 7/8.
The answer is -10x^3+23x^2-24x+18
