Split the second term in 4x^2 + 17x - 15 into two terms
4x^2 + 20x - 3x - 15
Factor out the common terms in the first two terms, then in the last two terms.
4x(x + 5) -3(x + 5)
Factor out the common term x + 5
<u>(x + 5)(4x - 3)</u>

Answer:
15.8 ft
Step-by-step explanation:
The inclined plane, the base of and the shelving unit form the shape of a right angled triangle.
The hypotenuse is the length of the inclined plane, h.
The base of the triangle is 15 ft.
The height of the triangle is 5 ft.
To find the hypotenuse, h, we have to use Pythagoras rule:

where a = height of the triangle
b = base of the triangle
Therefore:

The inclined plane is 15.8 ft long.
