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.
I’m learning this right now so first you will subtract 8 on both sides of the equation. Then, rewrite it as 12y=2x-8. Next you will divide by 12 to each number when you are done then rewrite it as y=1/6x-2/3. Then for x you will divide by 2 on both sides and it would be x=6y+4. Well, that’s how I’m learning it I don’t know if that’s the same way you are learning it. But there you go
Answer:
in 7 days level of water changed in lake= -28
the water level change each day= -28/7= -4cm
Step-by-step explanation:
He stop playing with his hamster at 4:06 because 3/5 of an hour is 36 minutes and 36 plus 3:30 is 4:06.
You said that (1/2) / N = 1/3
Multiply each side by 'N' : (1/2) = 1/3 N
Multiply each side by 3 : 3/2 = N
or 1-1/2 = N .
