Answer:
Step-by-step explanation:
Lets factor the trinomial 
step-by-step:
Step 1. Since all the terms are negative, we can factor -1 out
Step 2. Split the middle term of 
, so 
Step 3. Group common terms
Step 4. Factor each parentheses
Step 5. Factor the common binomial
Now, we can put it all together:
The solution to the problem is as follows:
<span>you have"a" as common so, you can write it as: a(3b+1) +3b^2 + b. from the remaining two terms, you have b common, so write it as a(3b+1) +b(3b+1).
This gives you (a+b)(3b+1)

Answer: B
Step-by-step explanation:
the area of land is 4.9*6.2*0.225=6.8355m^3 (6.8355m^3/0.87≈7.85 yes you have enough
Im pretty sure the answer is 92.0 becauese
if you do 10.5x3.5 5x5=25 5x0+2=7 5x1=5 so that will be 57.5 then your going to do 3x5=15 3x0+1=4 3x1=3 that equals 34.5 then your going to add 57.5 +34.5
= 92.0
