Answer:
(x+2)(x-5)
Step-by-step explanation:
Given the expression X^2−3x−10, we are to factorize it;
On factorizing;
= x² - 5x + 2x - 10
= x(x-5) + 2(x - 5)
= (x+2)(x-5)
Hence the factored form of the expression is (x+2)(x-5)
Answer:
9 rinks
Step-by-step explanation:
9 rinks can situate 108 girls and there are 107 so there will be enough if you did any less then there would be girls that couldn't play hokey.

Answer:
12
Step-by-step explanation:
There are many ways to approach this problem. I like a method that uses the least amount of computation. We could figure how much Wendy makes on a bag of chips, the additional amount Wendy wants to make, then divide the latter by the former to find the number of additional bags to sell.
We could use a proportion to figure the number of bags corresponding to $126 in earnings, then subtract the 72 bags already sold. Essentially, we will do this, but without the intermediate numbers.
__
The additional fraction of 72 bags will be ...
(126/108) -1 = 18/108 = 1/6
Then Wendy must sell an additional ...
(1/6)×(72 bags) = 12 bags
to increase her earnings to $126.
