Assuming that you mean that the sector is 7/16th of the area, we know that there are 360 degrees in a circle. To find 7/16th of that, we can simply multiply 360 by 7/16 to get 157.5 as the measure of the sector's arc in degrees
<span>x3 + 4x2 – 9x – 36
= x^2( x + 4) - 9(x + 4)
= (x + 4)(x^2 - 9)
= (x + 4)(x - 3)(x + 3)</span>
Answer:
-8/3 or -2.66666 or -2 2/3
Step-by-step explanation:
Move constant (+9) to the right side and change its sign (25 - 9)
Then subtract those numbers (=16)
Divide both sides by -6
