Hello!
1 foot = 12 inches
We need to convert 5 feet 6 inches to just inches. To do this, let's multiply how many inches there are in one foot by 5 feet.
12 × 5 = 60
That means that 5 feet are equal to 60 inches. We still have 6 inches left. Add them:
60 + 6 = 66
ANSWER:
5 fest 6 inches = 66 inches.
then the domain of (f•g)(x) is {-1, 1, 3/2}
Answer
x times y = xy
x + y times a + b = (x + y)(a + b)
For that you can use the FOIL method which is First, Outside, Inside, Last.
First: x times a = ax
Outside: x times b = bx
Inside: y times a = ay
Last: y times b = by
So you have ax + bx + ay +by.
If you end up using numbers, then you can simplify.
Ask your teacher or parents. It's easier to explain in person.
Just be patient: y = -sqrt(8.41) = calculator (negative value) and so on. The last one is 0! :)
