Answer:

Step-by-step explanation:

Because those 2 lines are parallel, then 2x + 10 and 2x - 30 are same side interior and are supplementary. Therefore,

2x + 10 + 2x - 30 = 180 and

4x - 20 = 180 and

4x = 200 so

x = 50

A architect wants to create a rectangular room in a house. She wants it to have a total area of 255 square feet, and it should b

Alex787 [66]

Answer:

The answer to your question is length = 21.73 and width = 11.73

Step-by-step explanation:

Data

Total area = 255 ft²

length = x + 10

width = x

Formula

Area of a rectangle = length x width

Substitution

255 = (x + 10)(x)

Expand

255 = x² + 10x

Equal to zero

x² + 10x - 255 = 0

Solve with the quadratic formula

$x = \frac{-10 +- \sqrt{10^{2} -4(1)(-255)}}{2(1)}$

x = $\frac{-10 +-\sqrt{100 + 1020}}{2}$

x = $\frac{-10 +- \sqrt{1120}}{2}$

x = $\frac{-10 +- 33.47}{2}$

x₁ = 11.73 x₂ = -21.73

There are no negative dimensions so the answer is 11.73.

Length = 11.73 + 10 = 21.73 ft
