Use the algebraic expressions for the length and width of Marlene's living room found in the
krok68 [10]

Answer:

<em>The area of Marlien's living room is 420 square ft</em>

Step-by-step explanation:

Before calculating the real dimensions of Marlien's living room, we must find the value of x.

Given the total shape of the house is a rectangle, then both widths must be equal and both lengths must be equal.

The widths are already written width identical expressions x-2+x, but the lengths are given as different functions of x. Equating both expressions, we have:

2x-10+x-2+\frac{1}{2}x-4+x-2=2x+2+\frac{1}{2}x-4+x-2

Simplifying:

-10 + x - 2 = 2

x = 10 + 2 + 2

x = 14

Since x=14 feet, the dimensions of Marlien's living room are

width=x=14 feet

length=2x+2=30 feet

Thus the area is:

A = 14*30 = 420 square ft

The area of Marlien's living room is 420 square ft

The sum of two numbers is 109. If four times the smaller number is subtracted from the larger number, the result is 4. What are
anygoal [31]

Let the numbers be x&y

X+y=109

Taking a as the smallest number we multiply by 4

So according to the question you will have this equation

Y(as the largest number) -4x=4. Y-4x=4

Then find y

Y=4x+4

Substitute y on the first equation to get a

X+y=109

X+4x+4=109

X=21

21+y=109

Y=88
