16a^4b^4 + 32a^3b^5 - 48a^2b^6
the GCF would be : 16a^2b^4....because the 16 is the highest coefficient that goes into 16,32,and 48. Then u just take the a with the smallest exponent and the b with the smallest exponent.
Answer:





Step-by-step explanation:
Part 1) Find the measure of angle 1
we know that
-----> by supplementary angles

Part 2) Find the measure of angle 2
we know that
-----> by alternate exterior angles
Part 3) Find the measure of angle 3
we know that
-----> by vertical angles
Part 4) Find the measure of angle 4
we know that
------> by corresponding angles
Part 5) Find the measure of angle 5
we know that
-----> by vertical angles
so

Part 6) Find the measure of angle 6
we know that
-----> by supplementary angles
we have

substitute


4/6
= (4/2) / (6/2)
= 2/3
6/12
= (6/6) / (12/6)
= 1/2
Because 2/3 ≠ 1/2, 4/6 and 6/12 are NOT equivalent.
The answer is A. he can make 1 in 2 hours
