This looks like a regular equation with substitution. so it would be
5(2) + 2(5) + 1
10 + 10 + 1
21.
If theres another way of going about doing this please inform me :]
Answer:
For the first one, just make sure the sides add up correctly and include the sides it gives. The prism will be 9x1x8 = 82 inches cubed.

Answer:
gradient = 9
Step-by-step explanation:
The gradient of the tangent at x = a is the derivative
Differentiate using the power rule on each term
(a ) = na and ( constant ) = 0
y = 2x² + 5x - 3
= 2.2 + 5 - 0
= 4x + 5
( x = 1 ) = 4(1) + 5 = 4 + 5 = 9 ← gradient of tangent
Volume of a sphere=(4/3)πr³ ⇒r=∛(3v/4π)
volume of a sphere=950 in³
Therefore:
r=∛(3*950 in³/4π)=6.09834... in≈6.1 in
answer: radius=6.1 in
