Answer:
53
reason:
substitute a with -7 and b with -37
this makes the equation (-7)3 - (-37)2, which equals 53

Answer:
34 Braids
Step-by-step explanation:
.85 per braid means 1 is 85 cents, 2 is $1.70 and so on. So normally you would just divide the total amount of money, so for instance if you had $2.55 you would be able to afford 3 braids, since 3 braids cost $2.55. in fact $2.56, $2.57 aaaaaaaaaaall the way up to $3.39 would be 3 braids, then $3.40 would be 4 braids.
Here though you first pay 3 dollars. so you need 3 first, then an extra 85 cents to get 1 braid. 2 braids is 3 dollars plus 1.70, 3 braids is 3 + 2.55 4 braids is 3 + 3.40 and so on.
So what you want to do is first take away that 3 dollars you need before the braids, then divide by .85. for instance $6.40 would get you 4 braids as I showed bcause 3 + 3.40 = 6.40. now 6.40 - 3 = 3.40 then 3.40 divided by .85 = 4
The problem says we start with$32, so lets do those steps. first 32 - 3 = 29. then 29 divided by .85 = 34.11. well it's not whole number so lets try something. 34 braids would be 3 + .85*34 = 31.90 and 35 braids would be 32.75 So 31.90, 31.91 aaaaaaaaall the way up to 32.74 would be 34 braids then 32.75 would be 35 braids. well, $32 is in that in between space, so it is 34 braids.
When I did 32 - 3 = 29. then 29 divided by .85 = 34.11 that 34.11 does actually tell us we wouldn't get to 35, I just wanted to make it very clear. so the answer is 34 braids.

Convert 10% into a decimal
(0.1)^{2} - (5%)^{2}
Remove parentheses around 0.1
0.1^{2}-(5%)^{2}
Raise 0.1 to the power 2 to get 0.1
0.01-(5%)^{2}
Convert 5% to a decimal
0.01-(0.05)^{2}
Remove parentheses around 0.05
0.01-0.05^{2}
Raise 0.05 to the power of 2 to get 0.0025
0.01-1*0.0025
Multiply -1 by 0.0025 to get -0.0025
0.01-0.0025
Subtract 0.0025 from 0.01 to get 0.0075
You Answer is: 0.0075
