Subtract "this" from "that" ⇒ "that" - ("this")
12x² + 3xy - 5y² - (8x²  + 3xy + 4y²)
12x² + 3xy - 5y² + -8x² - 3xy - 4y²        Subtraction means add the opposite
Now Combine like terms:
12x² - 8x² = 4x²
3xy - 3xy = 0
-5y² - 4y² = -9y²
ANSWER: 4x
² - 9y²

If you assume the samples are representative how many whole wheat bagels might you infer are sold at each store
Alexxandr [17]

Maurine owns three bagel shops. Each shop sells 500 bagels per day. Maureen asks her store managers to use a random sample to see how many whole wheat bagels are sold at each store each day. Shop A has total of 50 bagels in sample and 10 are whole wheat bagels. Store B has a total of 100 bagels in sample and 23 are whole wheat bagels. Shop C has 25 total bagels in sample and 7 are whole wheat bagels.

We find fraction of whole wheat bagels to the sample for each shop using given information

Shop A = \frac{10}{50}  = 0.20

Shop B = \frac{23}{100}  = 0.23

Shop C = \frac{7}{25}  = 0.28

The number of whole wheat bagels for each shop that sells 500 bagels per day

Shop A = 0.20 * 500= 100

Shop B = 0.23 * 500= 115

Shop C = 0.28 * 500= 140
