Answer:
A. Quadratic trinomial
Step-by-step explanation:
You can easily eliminate B and C because trinomial means there are three terms. B has monomial (one term) and C has binomial (two terms).
Now you have A and D. D is cubic which means the first term (4x²) would have to be cubed (4x³). Quadratic means it is squared.
Answer:
1/21
Step-by-step explanation:
Step-by-step explanation:
Fraction of work done by Gardner in 1 hr = 1 / 5
Fraction of work done by Gardner and helper in 1 hr = 1 / 4
Fraction of work done by helper in 1 hr
= 1 / 4 - 1 / 5
= 1 / 20
<u>Time required by helper to complete work</u> :
= <u>20 hours</u>
