Answer:
w = 7m
l =9 m
Step-by-step explanation:
Let w = width
l = w+2
A = l*w
63 = (w+2) * w
63 = w^2 +2w
Subtract 63 from each side
0 = w^2 +2w - 63
Factor
What 2 numbers multiply to -63 and add to 2
9*-7 = -63
9-7 = 2
0 = (w +9) ( w-7)
Using the zero product property
w+9 =0 w-7 =0
w = -9 w = 7
Since we cannot have a negative length
w=7
l =w+2 =7+2 = 9
Answer:
-12 =x
Step-by-step explanation:
3(x - 2) = 6(5 + x)
Distribute
3x -6 = 30 +6x
Subtract 3x from each side
3x-6-3x = 30 +6x-3x
-6 = 30+3x
Subtract 30 from each side
-6 -30 = 30+3x-30
-36 = 3x
Divide each side by 3
-36/3 = 3x/3
-12 =x
