You use Pythagorean theorem to solve this problem.a^2+b^2=c^2
A.53*53=45*45+28*28
2809=2025+784
2809=2809
B.85*85=13*13+84*84
7725=169+7056
7725=7725
C.85*85=36*36+77*77
7725=1296+5929
7725=7725
D.65*65=16*16+61*61
4225=256+3721
4225=3977
The answer is D
Yes but you have to post the question.
The GCF is 3*b = 3b
Step-by-step explanation:
The GCF is the Greatest Common Factor which will divide all the numbers whose GCF it is.
To find the GCF, we factorize the polynomials first
So,

We can see that only 3 and b are common in factors of both polynomials
So,
The GCF is 3*b = 3b
