The length of a rectangle is 3x-5 and the width of the rectangle is 2x+7. Find the perimeter.

The perimeter is 110 cm.

Step-by-step explanation:

The length of a rectangle is 3x-5 and the width of the rectangle is 2x+7. Find the perimeter.

if we condense that

Perimeter = 2(Length) + 2(Width)

Now we can see how the answer forms. If we plug in our equations from above:

100 = 2(3x + 5) + 2(2x)

Distributing

100 = 6x + 10 + 4x

can someone answer this question plz

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
