D
Divide the whole thing by 2
2(X^2+8x-5)
X^2+8x. =5
Half of 8 is 4 sq it so you add 16
X^2+8x+16= 5+16
(X+4)^2=21
Answer:
choice c. x = 6
Step-by-step explanation:
b(x) = (x+41, what is b—10)
it looks like b = x + 4
b = 10, then
10 = x + 4,
x = 6
Answer:
45
Step-by-step explanation:
Since angles 4 and 2 are the same, we will have to do x+30 is = to 2x+15. After that x= 15. Substitute x in x+30. Which results in 45
