Answer:
1. (t + s)(u + v).
2. (m + k)(n + 3).
Step-by-step explanation:
1. tu+tv+su+sv
Note that t is common in the first 2 terms and s is common to the last 2.
= t(u + v) + s(u + v)
Now u + v is common so we have:
(t + s)(u + v).
2. mn+3m+kn+3k
= m(n + 3) + k(n + 3)
= (m + k)(n + 3).
Answer:
If you round two decimal places, it should be 9.

Answer:
1/4
Step-by-step explanation:
We have 3/4 of a tank
We will use 2/3 of the gas in the tank
That will leave us 1/4
Mathematically
3/4*2/3 = 2/4 =1/2 this is the amount that is used
Subtract this from the amount in the tank
3/4 -1/2
3/4 -2/4 = 1/4
This is the amount that is left in the tank
