Hey there!

Answer = -21

Explanation:

Let's solve your equation step-by-step.

x + 7 = -14

Subtract seven from both sides:

x + 7 - 7 = -14 - 7

x = -21

So therefore, that is how you found your answer: x = -21

to find x you add would change -14 into 14 and add 14+ 7 and it will be 21 but x=-21 because your answer is a negative number

OLEGan [10]

Answer:

The dimensions are length=32 inches and width=24 inches

Step-by-step explanation:

Recall that perimeter of a rectangle is

P  = 2(w + l)

The ratio of its length to width is 4:3.

This implies that,

\frac{l}{w}  =  \frac{4}{3}  \\ l =  \frac{4}{3} w

We substitute P=112 inches, and l in terms of w to get;

112 = 2(w +  \frac{4}{3}w)

56 = w +   \frac{4}{3}w

168 = 3w + 4w

7w = 168

w =  \frac{168}{7}  = 24

The length is

l =  \frac{4}{3}  \times 24 = 32
