The excluded value is -16
C
Since in the original equation, there is √d, to isolate the variable, we must square both sides.
(√d)²= (4h)²
d= 16h^2
Final answer: d= 16h^2
Answer:
36x - 7
Step-by-step explanation:
Answer:
4x² + 20x - 2
Step-by-step explanation:
To evaluate (c ○ d)(x), substitute x = d(x) into c(x)
c(x² + 5x)
= 4(x² + 5x) - 2
= 4x² + 20x - 2
