Start with x^2 + 4x = 12 and complete the square, what is the equivalent equation?
*need it asap*

answer:

(x + 2)^2 = 16.

step-by-step explanation:

x^2 + 4x = 12

(x + 2)^2 - 4 = 12

(x + 2)^2 = 16.

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )
