My natural tendency is to FIOL instead of FOIL but it doesn't matter.

(x+5)(x-6)

Firsts: x times x

Outers: x times -6 = -6x

Inners: 5 x

Lasts: 5(-6)=-30

Outers+Inners = -6x + 5x = -x

Answer: -x

(x-2)(x-3)=x^2-3x-2x+6=x^2-5x+6

Answer: second choice

A rectangle has an area of 45x2 − 42x − 48 and a width of 5x − 8. what is the length of the rectangle? to find the length of the

kondaur [170]

If the area and width of the rectangle are 45x² − 42x − 48 and (5x − 8) then the length of the rectangle will be (3x + 2).

<h3>What is a rectangle?</h3>

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.

A rectangle has an area of 45x² − 42x − 48 and a width of 5x − 8.

Then the length of the rectangle will be

area = length × width

Then we have

Area = 45x² − 42x − 48

Then the factor of the polynomial will be

Area = (5x − 8)(3x + 2)

Then the length of the rectangle will be (3x + 2).
