Answer:
D
Step-by-step explanation:
To obtain f(g(x)) substitute x = g(x) into f(x), that is
f(10 - 5x)
= (10 - 5x)² + 5 ← expand (10 - 5x)²
= 100 - 50x - 50x + 25x² + 5 ← collect like terms
= 25x² - 100x + 105 → D
The height of the enlarged picture will be 20 in because 15 divided by 6 is 2.5 so you multiply 2.5 by 8 in and you get 20.
The answer would be 49 + 42b if you multiply 7*7 and 7*6b
