Question

The perimeter of the rectangle is 98 units.Find the value of x. 5x+1
4x+3.

Answer 1

Do
5x + 1 and
4x + 3
refer to the length and width of the rectangle?

Answer 2

yes

Answer 3

Well, do you know your formula for perimeter? :)

Answer 4

2L+2W i believe

Answer 5

That's right :)
Now if we just let
L = 5x + 1
and
W = 4x + 3

What does that give us? :D

Answer 6

(by the way)
if you let
L = 4x +3
and
W = 5x + 1
it really doesn't change anything :)

Answer 7

I get mixed up on the math part thats why i asked for help!!!!

Answer 8

Oh ok :)
As we know
our length is
L = 5x + 1

and our width is
W = 4x + 3

We know that the formula for perimeter is
P = 2L + 2W

We also know that the perimeter is 98.

So we just replace
P with 98
L with 5x + 1

and
W with 4x + 3

Which brings us to:
98 = 2(5x + 1) + 2(4x + 3)

Can you do the rest? :)
