1) 4x + 12x² + 9 + 3y + 2x + 11y
6x + 12x² + 14y + 9
2) x² + 2y + 15x² + 4x + 21
4x + 16x² + 2y + 21
3) 8x + 12 + 17y + 3x + y + 8
11x + 18y + 20
Hope this helps :)
Answer:
B
Step-by-step explanation:
You are making composite functions, since all the answers provided dont fit, I only suggest to clearify that the lone term in the B option, is actually 45x and not 45.
If this is the case, composite functions means that you eval the expresion g(x) in every x variable found in f(x).
Using this, it gives you that f(g(x))= 
Answer:
Volume = 202.5 cubic feet
Step-by-step explanation:
Given that the aquarium is in the shape of a right rectangular prism in which
Length L = 6 1/4 feet
Width W = 7 1/5 feet
Height H = 4 1/2 feet
Volume = L × B × H
Volume = 25/4 × 36/5 × 9/2
Volume = 5 × 9 × 4.5
Volume = 202.5 cubic feet
-x² + 8x - 6 = 0
x = <u>-(8) +/- √((8)² - 4(-1)(-6))</u>
2(-1)
x = <u>-8 +/- √(64 - 20)</u>
-2
x = <u>-8 +/- √(44)

x = <u>-8 + 2√(11)</u> x = <u>-8 - 2√(11)
</u> -2 -2<u>
</u>x = 4 - √(11) x = -8 + √(11)
