Which expression is equivalent to x2−12x+36? a (x+6)2

b (x+12)(x−3)

c (x+6)(x−6)

d (x−6)2 please help me figure this out

(x-6)(x-6) or (x-6)^2

Step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

246
