Question

find the perimeter of the rectangle 3x+6  5x-2

shamil98 · Answer

I'm guessing those are the values of the length of width.
If you recall the perimeter of a rectangle is
$$\large P = 2L + 2W$$

Shamil98 that is the right equation.

Ah, okay.

shamil98 · Answer

First, off, we want to solve for x.

anonymous · Answer

Thank you.

shamil98 · Answer

$$\large 3x + 6 = 5x -2$$
$$\large 8 = 2x$$
$$\large 4 = x$$

shamil98 · Answer

Evaluate the width.
3(4) + 6 
12 + 6
w = 18

Now back to your equation for perimeter.
p = 2l + 2w

p = 2(6) + 2(18)
simplify to get your final result.

what does the last part say? 4x+?

anonymous · Answer

4x+9

shamil98 · Answer

All sides are equal.
so.
9x - 11=  4x + 9
solve for x, and the evaluate either expression.

anonymous · Answer

i'm getting that wrong... please help me solve for x

shamil98 · Answer

9x - 11= 4x + 9
5x = 20
x = 4

4(4) +  9 
= 16 + 9
= 25

shamil98 · Answer

The perimeter is all the sides added.
triangles have three sides.
all sides are equal.
25 x 3 
= 75
