Answer:
6h^2 -4h -2
Step-by-step explanation:
(h^2 +4h -4) +(5h^2 -8h +2)
= h^2(1 +5) +h(4 -8) +(-4 +2) . . . . group like terms
= 6h^2 -4h -2
Answer:
7230 gallons
Explanation:
The total water pumped out is equal to 210 multiplied by 3 which equals to 630 gallons.
This gives the volume of the tank 3 days ago as 630 + 6600 = 7230 gallons
Answer: 3x⁵ - 2x⁴ - x² + x - 21
<u>Step-by-step explanation:</u>
f(x) = 3x⁵ + 6x² - 5
<u> - g(x)</u> = <u> -2x⁴ - 7x² + x - 16</u>
(f - g)(x) = 3x⁵ - 2x⁴ - x² + x - 21
Set up the composite function and evaluate
fg (x^2)=gx^4
