Use completing the square to solve the equation x2+16x=−44 . first determine the number you must add to both sides of the equation.

x = -8 ± √(56)

Step-by-step explanation:

    x2 +16x = -8    

Add 64 to both sides:                   x2 + 16x + 64 = -8 + 64

Factor and simplify:                     (x + 8)2 = 56

Use the square root method:     x + 8 = ± √(56)

Subtract 8 from both sides:        x = -8 ± √(56)                

b

Step-by-step explanation:

Yes

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
