The GCF of 28 and 16 is 4 since 28/4=7 and 16/4=4 and 7 and 4 are relatively prime. The gcd of a^3 and a is a. The gcd of b and b^2 is b. Thus, the gcd of the whole thing is 4ab so A is the answer.
Answer:
3/2 = 1/ 1/2
Step-by-step explanation:
1 1/5 divided by 4/5 is 1 1/2
It is NOT a right triangle because a^2+b^2 does not equal c^2.
