Subtract the powers
c. 9-7 so 10^2
d. 8-1 so 5^7
Assuming the exponent is supposed to be "^2" your equation will read:
4x² + 8x - 5
It must set equal to y to be a valid function and the y must be set equal to zero to find x-intercepts.
4x² + 8x - 5 = 0
4x² - 2x + 10x - 5 = 0
2x(2x - 1) + 5(2x - 1) = 0
(2x + 5)(2x - 1) = 0
Set each binomial equal to zero.
2x + 5 = 0
2x = 0 - 5
2x = - 5
Divide both sides by 2
x = - 5/2
2x - 1 = 0
2x = 0 + 1
2x = 1
x = 1/2
Your x-intercepts are x = - 5/2, 1/2 or (- 5/2, 0) and (1/2, 0)

The answer to your question is 37.5.
Answer:
We can take 2 plates , 3 plates or 6 plates.
Step-by-step explanation:
1 dozen = 12 numbers
Total number of cookies = 42
Each plate has to get atleast 7 cookies ,all the plates should have the same number of cookies and also the number of plates must be greater than or equal to 2.
- If we take 2 plates , there can be 21 cookies in each.
- If we take 3 plates , there can be 14 cookies in each.
- If we take 6 plates , there can be 7 cookies in each.
These are the 3 possible cases.
Since there cannot be broken pieces, no other combination is possible.
