20% x 50 =(20 / 100) x 50 = (20 x 50) / 100 = 1000 / 100 = 10
answer is 10
Answer:
12
Step-by-step explanation:
To find f(-2), substitute (-2) into x of the function f(x) = 4x^2-2
We get, f(-2) = 4(-2)^2 - 2
= (4*4)-2 = 16-2 = 14
Therefore, f(-2)=14.
Let's set the measure of each angle equal to 540 degrees.
4x + 4x + 5x + 2 + 96 + 5x - 8 = 540
Combine like terms.
18x + 90 = 540
Subtract 90 from both sides.
18x = 450
Divide both sides by 18
x = 25
