Answer:
(x -1)(12x +13)
Step-by-step explanation:
You are looking to rewrite the middle term as the sum of terms that have factors of (12)(-13) that have a total of +1. Those factors are -12 and +13, so the expression you are factoring by grouping is ...
12x^2 +13x -12x -13
= x(12x +13) -1(12x +13)
= (x -1)(12x +13)
Answer: <u>The factors of 72 are: 1,2,3,4,6,8,9,12,18,24,36,72. So basically 12, and if 72 doesn't count than it is 11.</u>

8 apples/15 minutes
16 apples/x minutes
8/16=1/2
2*15=30
30 minutes
x = 2
solve 4x + 6 = 2x + 10
subtract 2x from both sides
2x + 6 = 10
subtract 6 from both sides
2x = 10 - 6 = 4
divide both sides by 2
x = = 2
as a check f(2) =(4 × 2 )+ 6 = 14 and g(2) =( 2× 2) + 10 = 14
For the first question the answer is (2,2) and for the second question the answer is (0,4)
