Answer:
(f + g)(x) = 3x² + x + 5
(f - g)(x) = 3x² - x - 3
Step-by-step explanation:
(f + g)(x) → f(x) + g(x) → <u>3x² + 1</u> + <u>x + 4</u>
Combine like terms and you get: 3x² + x + 5
(f - g)(x) → f(x) - g(x) → <u>3x² + 1</u> - (<u>x + 4</u>)
Remember to distribute the neg. everything in the parentheses. Combine like terms and you get: 3x² - x - 3
It would be w(5•4) because she reads 20 pages in one week. then you can multiply 20 by any number of weeks to get that number of pages in total.

Answer:
D. 52a^2 + 26
Step-by-step explanation:
6( 4a^2 + 11a) - 13( 5a - 2) - a + 4( 7a^2 )
24a^2 + 66a - 65a + 26 - a + 28a^2
52a^2 + 26
hope this helps!
