Ok
7.12^2 = 24in^2
8.put 400 for each x and see what is close to the nearest tenth
9.u reverse it 6-9=? then square root ?
and 10. u do the same as nine and 1 more number to subtract
We have the rational expression

; to simplify it, we are going to try to find a common factor in the numerator, and, if we are luckily, that common factor will get rid of the denominator

.
Notice that in the denominator all the numbers are divisible by two, so 2 is part of our common factor; also, all the terms have the variable

, and the least exponent of that variable is 1, so

will be the other part of our common factor. Lets put the two parts of our common factor together to get

.
Now that we have our common factor, we can rewrite our numerator as follows:

We are luckily, we have

in both numerator and denominator, so we can cancel those out:


We can conclude that the simplified version of our rational function is

.
Answer: The distance in the map is 19 inches.
Step-by-step explanation:
On the map. 2 inches represent an actual distance of 64 miles.
The actual distance between town A and town B is equal to 608 miles, we need to divide this distance into groups of 64 miles.
N = 608/64 = 9.5
And each one of those 9.5 groups is represented with 2 inches in the map, then the distance in the map is:
d = 9.5*2 inches = 19 inches.
I believe so yes this is correct I think
Step-by-step explanation:
(x−1)²−9=0
(x-1)²= 9
x-1 = ±√9
x-1 = ±3
x = 1-3=-2 or x=1+3=4
the solution = {-2,4}
