The perimeter of a rectangle is 30 inches. If the length of the rectangle is 10 inches, which equation could be used to find the width, x?
A.
10(x + 2) = 30

B.
x + 10 = 30

C.
2(x + 10) = 30

D.
x + 2(10) = 30

Answer:

The correct answer is c. 2(x+10)=30

Step-by-step explanation:

The equation to solve for perimeter is 2(w+l)=p or 2(width+length)=Perimeter.  

Thus, the only thing we have to do is substitute the known values into the equation.

The perimeter is 30 and the length is 10, so substitute that in.

This leaves us with the equation 2(w+10)=30 and since we are only trying to find one variable, we can change w to x.

Hope this helps!

Answer:

The right option is C) 2(x+10) = 30

Step-by-step explanation:

The perimeter of a rectangle is given by

P= 2 (l + w )

By putting the values

P = 2 (30 + x )

and 2(x + 10) = 30

which is option C
