Answer:
See below
Step-by-step explanation:
3 (x^2 + 3x) = 4
3 ( x + 3/2)^2 = 4 + 27/4
Answer: y+6x = -34
<em><u>Step-by-step explanation:</u></em>
y-2= -6(x+6) (<u><em>Ax+By=C is the goal)</em></u>
y-2= -6x-36 <u>(-6) x & (-6) 6</u>
y=-6x-34 (Add 2 to both sides)
<em>y+6x = -34 [Add 6x to both sides]</em>
