This is pretty simple once you get used to this

First set it equal to the original and the negative one

(>_) is the bigger and equal to part

4x+5>_45 or 4x+5>_-45

Then solve for x for both

4x>_40. 4x>_-50

X>_10 X>_-25/2

2(x^2+6x+9) = 2(x+3)^2

So after divided by (x+3), answer will be:

2(x+3)

B because 75$ + 50$ h (each hour) = cost

4/10. Just have to look up what fractions are equivalent to 2/5 and look at the number that has 10 as a ‘denominator’

Remove the decimal and put the number over 1000 or the next highest mark(10,100,1000,10000,etc depending on how many figures are in the number)

226/1000

Then divide the two by the Greatest Common Factor. In this case, it will be 2.

**113/500**

You cannot divide this any further because 113 is a Prime number, and 500 is not divisible by 113.
