Answer:

(x - 9)(x + 8)

Step-by-step explanation:

Given

x² - x - 72

Consider the factors of the constant term (- 72) which sum to give the coefficient of the x- term (- 1)

the factors are - 9 and + 8, since

- 9 × 8 = - 72 and - 9 + 8 = - 1, thus

x² - x - 72 = (x - 9)(x + 8)

Circle L is shown. Line segments K L and M L are radii. The length of K L is 12. Angle M L K is 60 degrees. Sector M L K with a

sergejj [24]

Answer:

$120\pi$ square units

Step-by-step explanation:

We are given that

Radius of circle=12 units

Angle MLK=60 degree

We have to find the area of sector that is not shaded.

Area of shaded sector MLK= $\frac{\theta}{360}\times \pi r^2$

Area of shaded sector MLK= $\frac{60}{360}\times \pi(12)^2=$ 24 square units

Area of whole circle= $\pi r^2=\pi (12)^2=144\pi$ square units

Area of sector that is not shaded =Area of whole circle-Area of shaded sector MLK= $144\pi-24\pi$

Area of sector that is not shaded= $120\pi$ square units
