Answer:
Let the number of five's = 2x = 2x × 5 = 10x
Then the number of ten's = x = x × 10 = 10x
10x + 10x = 640
20x = 640
x = 32
There are 32 ten dollar bills.
I'm not sure but from where i can see the first factor is the value of the product just simplified.
Answer:
(8x - 9y)2
Step-by-step explanation:
64x2−144xy+81y2
Equation at the end of step 1:
((64 • (x2)) - 144xy) + 34y2
The Equation at the end of step 2:
(26x2 - 144xy) + 34y2
Step 3:
(8x - 9y)2
