Width = x then length = 2x
2x * x = 18
x^2 = 18/2 = 9
x = 3
So the width = 3 feet and the length = 6 feet.
Answer:
x=-7
y=6
Step-by-step explanation:
7x+10y=11
4x+3y=-10
-3(7x+10y=11
10(4x+3y=-10
-21x-30y=-33
40x+30y=-100
19x = -133 (divide 19 on both sides)
x= -7
Now put the x in one of the original questions.
7(-7)+10y=11
-49+10y=11 (Add 49 to both sides)
10y=60 (Divide 10 on both sides)
y=6
Answer:
2 + 2w
w = 9.3in
l = 20.7 in
Step-by-step explanation:
Perimeter of a rectangle = 2 x (length + breadth)
legnth = 2 + 2w
width = w
2 x (2 + 2w + w ) = 60
(2 + 2w + w ) = 30
2 + 3w = 30
3w = 28
w = 9.3
length = 2 + 2x9.3 = 20.7
