FOIL is a mnemonic rule for multiplying binomial (that is, two-term) algebraic expressions.
FOIL abbreviates the sequence "First, Outside, Inside, Last"; it's a way of remembering that the product is the sum of the products of those four combinations of terms.
For instance, if we multiply the two expressions
(x + 1) (x + 2)
then the result is the sum of these four products:
x times x (the First terms of each expression)
x times 2 (the Outside pair of terms)
1 times x (the Inside pair of terms)
1 times 2 (the Last terms of each expression)
and so
(x + 1) (x + 2) = x^2 + 2x + 1x + 2 = x^2 + 3x + 2
[where the ^ is the usual way we indicate exponents here in Answers, because they're hard to represent in an online text environment].
Now, compare this to multiplying a pair of two-digit integers:
37 × 43
= (30 × 40) + (30 × 3) + (7 × 40) + (7 × 3)
= 1200 + 90 + 280 + 21
= 1591
The reason the two processes resemble each other is that multiplication is multiplication; the difference in the ways we represent the factors doesn't make it a fundamentally different operation.
Answer:
Part A) The percentage increase was 
Part B) Michael is financially better off this year than last year
Step-by-step explanation:
Part A)
we know that
Using proportion
Let
x-----> the percentage increase
Part B) Compare the percentage increase with the inflation
The percentage increase is greater than the inflation
therefore
Michael is financially better off this year than last year
Not sure:((((((( sorrryyyy
For question 2 it is 15
Because: 4 time 6 is 24 and then you minus 9 which is 15
So there you have it the answer is 15
