Write an equivalent expression. - 2(5+ 7g)
Choose the correct answer below.
OA. – 2(5 + 7g) = 7g - 10
OB. – 2(5 +79) = - 2 - 14g
OC. – 2(5 + 7g) = - 10 - 14g
OD. – 2(5 + 7g) = - 10 + 7g

answer: 0+0=0

step-by-step explanation:

that is the only answer that can make 0

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
