Answer:
No.
Step-by-step explanation:
Let d represent the number of dimes. Then the number of quarters (according to the friend) is d+8. The total value is
... 10d +25(d+8) = 280 . . . . in cents
... 35d + 200 = 280 . . . . . . eliminate parentheses
... 35d = 80 . . . . . . . . . . . . . subtract 200
... d = 80/35 = 16/7 = 2 1/7 . . . . . not a realistic number of coins
_____
The difference between the number of quarters and the number of dimes may be any multiple of 7.
Answer:
88,306
Step-by-step explanation:
Multiplying times 7 steps:
Step 1. 8 x 7 = 56
Step 2. 1 x 7 = 7
Step 3. Add the 5 from step 1. 7 + 5 = 12
Step 4. 3 x 7 = 21
Step 5. Add the 1 from step 3. 21 + 1 = 22
Step 6. 1 x 7 = 7
Step 7. Add the 2 from step 5. 7 + 2 = 9
Equals = 9226
Steps for times 6:
Step 1. 6 x 8 = 48
Step 2. 1 x 6 = 6
Step 3. Add the 4 from step 3. 6 + 4 = 10
Step 4. 3 x 6 = 18
Step 5. Add the 1 from step 3. 18 + 1 = 19
Step 6. 1 x 6 = 6
Step 7. Add the 1 from step 5.
Equals = 79080
Now add the two 9226 + 79080 = 88, 306

Step-by-step explanation:
((7x-4)^2) - (7x-4)(7x-4) + 3
(7x-4)(7x-4) is 7x-4^2
So its (7x-4)^2 - (7x-4)^2 + 3
(7x-4)^2 cancel out.
