232 − 172 = 529 − 289 = 240
232 − 172 = (23 + 17)(23 − 17) = (40)(6) = 240
232 − 172 = (23 − 17)2 = (6)2 = 36
Answer:
Your answer is 23^2 − 17^2 = (23 + 17)(23 − 17) = (40)(6) = 240, or C on your answer sheet.
Step-by-step explanation:
Lets begin!
So when a binomial is composed of two perfect squares separated by a subtraction symbol, a certain method called the difference of perfect squares can be used. The difference of perfect squares method can be done by multiplying the sum and difference of the two square roots.
So, to solve:
23^2 - 17^2 = (23 + 17)(23-17) = (40)(6) = 240
Thus being your answer.

Answer:
10.33m/s
Step-by-step explanation:
Vfinal - Vinitial/time = acceleration
To solve this problem we have to first identify the data that we need and is important. You can arrange it like this:
Current Cost of Cereal: $3.39
CPI: 289.7
To find the cost of a box of cereal in 1983 we will need to use the following formula:
Cost in Base Year = Current Cost/CPI*100
Replace the data in the formula and we get the following:
1983 = 3.39/289.7*100
In 1983 the cost of a box of cereal was $1.170176044
I hope this helps, Regards.
