The length of a rectangular room is 8 feet more than twice the width. If takes perimeter of the room is 124 feet, what are its d
Vlad1618 [11]

Hey there! I'm happy to help!

Let's call the length and width L and W respectively.

L=2W+8

2W+2L=124

We plug our value of L into the second equation and solve for W.

2W+2(2W+8)=124

We undo the parentheses with the distributive property.

2W+4W+16=124

Combine like terms.

6W+16=124

Subtract 16 from both sides.

6W=108

Divide both sides by 6.

W=18

We plug this W value into the first equation to solve for L.

L=2(18)+8

L=36+8

L=44

So, the length is 44 feet and the width is 18 feet.

Have a wonderful day! :D

The human population doubles approximately every 50 years if there were 2.5 million people in 1950 how many people are forecaste
Margarita [4]
The equation that would let us determine the number of people or population at a certain year is calculated through the equation,

    A(t) = A(o)(2^(t - 1950)/50)

Substituting the known values,

   A(t) = (2.5 million people)(2^(2100 - 1950)/50))

   A(t) = 20 million 

<em>Answer: 20 million people</em>

What’s a number that multiplies to four but adds to three
d1i1m1o1n [39]

Answer:

The answer is clearly 4 and 1. If we change the sign on 1 (making it -1), then you have the answer to your original question. 4 and -1 multiply to -4 and add up to 3.
