What is the value of f(−6) when f(x)=x2+8x+10?

-2

Step-by-step explanation:

given:

f(x) = x² + 8x + 10

for f(-6), simply substitute x = -6 into the right side of the equation

f(-6)

= (-6)² + 8(-6) + 10

= 36 - 48 + 10

= -2

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
