14. Michelle simplified an expression for the perimeter of the rectangle below and got X + 35.

Zigmanuir [339]

Answer:

The correct expression for the perimeter is $P=(\frac{5}{3}x+70)\ units$

see the explanation

Step-by-step explanation:

The complete question in the attached figure

Let

L ----> the length of rectangle

W ---> the width of rectangle

we know that

The perimeter of rectangle is equal to

$P=2(L+W)$

In this problem we have

$L=(\frac{5}{6}x+23)\ units$

$W=12\ units$

substitute the values

$P=2(\frac{5}{6}x+23+12)$

$P=2(\frac{5}{6}x+35)$

$P=(\frac{10}{6}x+70)\ units$

Simplify

$P=(\frac{5}{3}x+70)\ units$

Michelle didn't multiply the sum of length and width by 2

The area of a rectangle is 128 ft.² if the link is twice the width what is the measure of the width of the rectangle

andrew-mc [135]

Let, the width = x
Then,Length = 2x

Now, Area = l * w
A = (2x)(x)
128 = 2x²
x² = 128/2
x = √64
x = 8

In short, Your Answer would be 8 Feet

Hope this helps!
