Step-by-step explanation:
put it in least to greatest and then put your fingers on the opposite side of the numbers and count down at the same time
The first equation is
The second equation is
If you sum the two equations you'll cancel y:
And since the sum must be 11, we have y=9.
Answer:
L = 12
W = 8
Step-by-step explanation:
Area = L*W
L = W + 4
W = W
Area = 96
W ( W + 4) = 96
w^2 + 4W = 96
w^2 + 4w - 96 = 0
(w - 8)(w + 12) = 0
Only w - 8 = 0 will work
w - 8 = 0 Add 8 to both sides
w = 8
w + 12 = 0 will not work because you have to subtract 12 from both sides to get the value for w.
w = - 12 which has no meaning for garden plots.
So the width = 8 and the length = w + 4 = 8 + 4 = 12
Answer:
30, 24+6
Step-by-step explanation:
So the negative in front of the parentheses turns it into a positive number.
