Answer:
2a(b^3 - 7b + 8)
Step-by-step explanation:
I'm assuming that 2a2b3 is 2a2b^2. If not, this answer isn't correct.
Look at the whole numbers. Is there a number that divides into them evenly? Yes, 2, so you pull 2 from the problem and divide each number by 2. Do the same for each variable.
2a2b3 - 14ab + 16a
2(ab^3 - 7ab +8a)
2a(b^3 - 7b + 8)
Answer:
the answe is 187 cm square
Answer: A
Step-by-step explanation:
Base case: For 
, the left side is 2 and the right is 
, so the base case holds.
Induction hypothesis: Assume the statement is true for 
, that is
We want to show that this implies truth for 
, that
The first 
terms on the left reduce according to the assumption above, and we can simplify the 
-th term a bit:
so the statement is true for all 
.
Alright, so in PEMDAS, we first do exponents. 3^2=9, and we then have 5(9)-3(3)+2. After that, we have multiplication, where we have 5*9 =45 and 3*3=9, resulting in 45-9+2 and eventually 38
