Answer:
Factored form is 4x(2x+3)
Step-by-step explanation:

The factors are
8x^2 ----> 2*2*2*x*x
12x -------> 2*2*3*x
GCF is 2 * 2 * x= 4x
Now we factor out GCF from 8x^2 + 12x
When we factor out GCF, divide each term by 4x

4x(2x +3)
Factored form is 4x(2x+3)
Answer:
your question is really not clear but if you were to put the -4 in the Y then the answer would be X=1/3, if you plug in -4 for X and find Y then Y = -17
Step-by-step explanation:
plug in -4 in Y
-4=3x-5 add 5 on both sides,
1 = 3x divide 3 on both sides
1/3= x
plug in -4 in X
y = 3(-4)-5 multiply 3 and -4 = -12
y = -12-5 subtract the -12 and -5 = -17
y = -17
