Hi , you have to divide the numerator and the denominator , if you get a decimal you just have to move the period 2 spaces to the right.
For example
3/8 -0.375
0.375 - 37.5

Answer:
(x+4)
Step-by-step explanation:
Solve by factoring. Think about what numbers multiply to be -36 (the last term) BUT also subtract/add up to be -5, which is the middle term. The answer to this is 4 and -9. Therefore, the two factors are (x-9)(x+4)
The radius of the circle,
Pi × r² = 144 pi
r ² = 144
r = 12
The area of the sector,
60 / 360 × pi × 12² = 144/6 × 22/7 or 3.142
= 75. 43 or 24 pi
