Answer:
- (a-2)(3a-5)
- (b-3)(5b-17)
Step-by-step explanation:
Recognize that b-a = -(a-b). (Reversing the order of a difference changes its sign.)
1. 3(a-2)² -(2-a) = 3(a-2)² +(a-2) = (a-2)(3(a-2) +1)
... = (a -2)(3a -5)
2. 2(3-b) +5(b-3)² = (b -3)(-2 +5(b -3))
... = (b -3)(5b -17)
They have enough balloons because I used division as my operation. 3 can go into 16 five times. I got 1 after subtracting and bring down 2. 3 can go into 12 evenly 4 times. 12 minus 12 equals 0 with no remainder. So, they get 54 balloons for each group. But I want to know how many EACH student gets enough balloons. 54 divided by 6 groups equals 9 balloons for each student.

Answer:
14, 96,84
Step-by-step explanation:
8n - 16 + 6n = 180 {Supplementary angles}
<u>8n + 6n</u> -16 = 180
Combine like terms
14n - 16 = 180
Add 16 to both sides
14n = 180 + 16
14n = 196
Divide both sides by 14
n = 196/14
n = 14
8n - 16 = 8*14 - 16 = 112 - 16 = 96
6n = 6 *14 = 84
