Expand
distributive property
a(b+c)=ab+ac
so
-(x-4)=-1(x-4)=-1(x)-1(-4)=-x+4
now we has
2x-x+4=5
2x-1x+4=5
1x+4=5
minus 4 both sides
x+4-4=5-4
x+0=1
x=1

2x - x + 4 = 5

so, x = 1

The perimeter of a rectangle is 132 feet and its area is 1080 square feet. find the dimensions

FrozenT [24]

2x + 2y=132

xy=1080

Let x=1080/y

2160/y + 2y=132
2y^2 - 132y +2160=0
2(y^2-66y+1080)=0
2(y-30)(y-33)=0
y=30 or y=33
(36,30) or (30,36)

So... x=30,36 and y=36,30. Either way, the answer is 30 by 36 or 36 by 30.
