Answer:
a) (2x+7)(x-4)
b) x = -7/2 and x = 4
Step-by-step explanation:
a) (2x ?)(x ?)
set up the above and considered factors of 28 that, when paired with 2, would give me -1x and -28 → (1·28, 2·14, 4·7)
after trial-and-error, found that 4 and 7 worked (used un-FOIL)
b) 2x + 7 = 0
2x = -7
x = -7/2
*********
x-4 = 0
x = 4

Step-by-step explanation:
I can't really explain my process since some are self explanatory, but if you do have questions, always know that you can reply and I'll answer them. Also, number four is cut off so I'm not sure if there is a fill in a blank portion there.
It helps you because it makes it easier to divide you just have to keep using place value to find the quitent

Step-by-step explanation:
Hello,
I am going to start with to change to a improper fraction:
1. I will convert 6 and 9/10 into a improper fraction:
2. Now that I have converted the mixed fraction into a improper I can multiply the numerator and the denominator.
3. Now I can simplify this value and convert it into a mixed fraction
After further simplifying I can convert this into an mixed number
