A contractor is hired to build an apartment complex. Each 840-square-foot unit has a bedroom, kitchen, and bathroom. The bedroom
Dennis_Churaev [7]

Answer:

350 sq ft

Step-by-step explanation:

Given that:

840 sq ft area has a bedroom, kitchen and bathroom.

Let the area of bedroom be x sq ft.

Then the area of kitchen will also be x sq ft.

Let the area of bathroom be y sq ft.

As per question statement:

x+y+x=840\\\Rightarrow 2x+y=840 ...... (1)

Tiles ordered to cover two kitchens and two bathrooms is 980 sq ft.

i.e.

2x+2y=980 ..... (2)

Subtracting equation (1) from (2):

i.e. (2) - (1):

y = 140 sq ft

Putting the value of y in (1):

2x+140=840\\\Rightarrow 2x =700\\\Rightarrow \bold{x=350\ sq\ ft}

Therefore, the carpet needed for each bedroom = <em>350 sq ft</em>

rearrange into quadratic form ax^2+bx+c=0. . 0.20= x^2/(25-x). . where a=1, and identify values of b and c
vivado [14]
Simplifying 0.20 = x^2 / (25 - x):

Multiply both sides by (25 - x)
0.20(25 - x) = x^2

Distributing 0.20:
5 - 0.20x = x^2

Placing all equations on to one side:
x^2 + 0.20x - 5 = 0

Where:
a = 1
b = 0.20
c = -5
