Let width be x, 
Length: 3+x 

P=2(l+w) 
54=2(x+(x+3)) 
54/2=2x+3 
27=2x+3 
27-3=2x 
24=2x
24/2=x 
12=x 

Therefore, the width is 12 inches and the length is (12+3)=15 inches

Hope I helped :)

-15.6 = -3.9r<br> please include an explanation of how you got your answer :) thanks
Mumz [18]

Here is the equation:

-15.6 = -3.9r

Since both decimals are negative, the answer will be positive.

  • Negative times Negative = Positive

Divide both sides by -3.9 to leave the variable alone:

-15.6 \div -3.9  = -3.9r \div -3.9 \\ 4 = r

r is equal to 4 → r = 4

Explain how to find the estimated sum of <br><br><br> 5<br> 8<br> +<br> 2<br> 9<br> .
mina [271]

The estimated sum of the numbers fifty-eight (58) and twenty-nine (29) is equal to ninety (90).

<h3>What is the difference between a regular sum and an estimated sum?</h3>

In an estimated sum, the numbers are rounded; on the other hand, in a regular sum, the numbers are not changed.

<h3>What is the estimated sum of 58 and 29?</h3>

1. Round the numbers:

  • 58 = 60 as this number is nearest to 60 than to 58.
  • 29= 30 because of the same reason explained above.

2. Add the rounded numbers:

  • 60 + 30 = 90

Which best describes the structure of the expression (5 ⋅ 46.4) − (3.2 ⋅ 13.7)
aksik [14]
You are subtracting the results in the parenthesis.

I would go with a difference. 

Since 8 is being multiplied by 23.6 and -7.8, I would say product.

"A" is the best answer choice.

I hope this helps!
