The answer is 14 because you have to substitute every answer with x and find which one both are equal to each other because both sides of the triangle are equal it is an equilateral triangle so the angles need to be congruent.

Find the circumference of a circle with an area of 28.26.<br> Show work please.
muminat

Answer:

18.84

Step-by-step explanation:

Since the formula for circumference is C=2\pi r, we need to first find the radius. The formula for the radius is r=\frac{\sqrt{A\pi } }{\pi }, so we will get r=3. Substitute that into C=2\pi r, and we get C=18.84. Hope this helps!

14. A rectangle has a width described by the expression (x2 + 2x – 15)/x and a length described by the expression
tensa zangetsu [6.8K]

Answer:

The answer to your question is Perimeter = [4x³ + 14x² + 50x - 150] / x(5 + x)

Step-by-step explanation:

Data

Width = (x² + 2x - 15)/x

Length = (3x² + 4x)/ (5 + x)

Process

1.- Write the formula for the perimeter of a rectangle

Perimeter = 2W + 2L

2.- Substitution

Perimeter = 2(x² + 2x - 15)/x + 2(3x² + 4x)/(5 + x)

3.- Simplification

Perimeter = (2x² + 4x - 30)/x + (6x² + 8x)/(5 + x)

4.- Sum the fractions

Least common factor = x(5 + x)

Perimeter = [(2x² + 4x - 30)(5 + x) + (x(6x² + 8x)] / x(5 + x)

-Simplification

Perimeter = [10x² + 20x - 150 - 2x³ - 4x² + 30x + 6x³ + 8x²] / x(5 + x)

Perimeter = [4x³ + 14x² + 50x - 150] / x(5 + x)
