Lets try substitution5x+2y=21=5x=21-2y=x=(21-2y)/5
sub into second equation
-2(21-2y)/5+6y=-34(-42+4y)/5+6y=-34solve for yy=-64/17plug into equation and solve for x=(97/17)

The answer is Net A with a surface area of 390 square inches
L =
- W
P = 2L + 2W = 2(L + W) → ( take out common factor of 2)
divide both sides by 2
= L + W
subtract W from both sides
- W = L
Answer:
y=-2
Step-by-step explanation:
because it's parallel --> a=-2
therefore we have y=-2x+b
the line goes through the point (3,-6) --> (-2).3+b=-6 --> b=0
