In a square the sum of the length of three sides is 48 and in a rectangle the same as a side of the square how is long is a length of the rectangle?

In a square, the sum of the lengths of three sides is 48 and in a rectangle

the difference between a length and a width is 7 in.

If a width of the rectangle is the same as a side of the square, how long is a length of the rectangle?

:

Let s = side of the square and the width of the rectangle

:

"In a square, the sum of the lengths of three sides is 48"

3s = 48

s = 48/3

s = 16

:

" in a rectangle the difference between a length and a width is 7 in."

L = s + 7

L = 16 + 7

L = 23 is the length of the rectangle

Step-by-step explanation:

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
