Answer:
x^2 + 2x -6
Step-by-step explanation:
f(x) = 2x+ 1
g(x) = x^2 - 7
(f+ g)(x)= 2x+ 1 + x^2 - 7
Combine like terms
= x^2 + 2x -6
70*300
=70(100+100+100)
=7,000+7,000+7,000
=21,000
Answer:
The widths and depths are the same. Since volume is length x width x height, you get 2x2x4=16, 3x3x6=54, 4x4x8=128, 5x5x10=250
