The rectangle has a length of 5x - 10 and a width of 2x. The perimeter is 120 units. Solve for x and use it to identify the actual length and width.

x= 10

Step-by-step explanation:

l= 40

w=20

P=l+w+l+w

120=5x-10+2x+5x-10+2x

120= 14x-20

120+20=14

140=14x

x=10

x=10

L=40

W=20

Step-by-step explanation:

P=2L+2W

120=2(5x-10)+2(2x)

120=10x-20+4x

120=14x-20

14x=140

x=140/14=10

then substitute

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false
