11s-9 is the answer to ur question
F(x) = 2x² + 7x - 5
g(x) = -8x² - 3x + 5
g(x) + f(x)
-8x² - 3x + 5 + 2x² + 7x - 5
-8x² + 2x² - 3x + 7x + 5 - 5
-6x² + 4x + 0
-2x(3x - 2)
Answer:
613 inches
Step-by-step explanation:
Area right triangle = 10,710
Formula for area of a triangle = 1/2(base x height)
We need to find the base because height and area is given
Reverse divide by 2 by doing multiply by 2
10,710 x 2 = 21420
Revers multiply by 612 by dividing by 612
21420 / 612 = 35
Base = 35
Formula for hypotenuse = a² + b² = c²
In this case a = 35, b = 612, and c = hypotenuse
35² + 612² = c²
1225 + 374544 = c²
375769 = c²
Square root of 375769 = 613
Hypotenuse = 613

Answer:
C. 48.
Step-by-step explanation:
If the mean is 12, then 12 must be 2x, 3x, 4x, and 3x divided by 4.
--> 
--> 
--> 
--> x=4
Add: 2x+3x+4x+3x=8+12+16+12=48
