1. (10x-y)² (because 100x²=(10x)², and -20xy=-2(10x)*y)
2. (2x+7y)(2x-7y) (because 4x²=(2x)², 49y²=(7y)²)
3. -2x²+8x-10
4. -12x^5+14x³-2x²+10x (use distributive property, multiply every term in the parenthesis by -2x)

Jill has $1.25 in her pocket. The money is in quarters and dimes. There are a total of 8 coins. How many quarters and dimes does
erica [24]

Answer:

  • 3 quarters
  • 5 dimes

Step-by-step explanation:

Let q represent the number of quarters (the higher-value coin). Then 8-q is the number of dimes, and Jill's total amount in change is ...

  0.25q +0.10(8-q) = 1.25

  0.15q + 0.80 = 1.25 . . . . . . . eliminate parentheses

  0.15q = 0.45 . . . . . . . . . . . . . subtract 0.80

  q = 3 . . . . . . . . . . . . . . . . . . . . divide by 0.15

  the number of dimes is 8-q = 8-3 = 5.

Jill has 3 quarters and 5 dimes.
