Obtuse, if that’s what you mean.
Answer:
Step-by-step explanation:
we have the equation of distance between two points :
d=
first point (21,5)
second point (28,-1)
so we have
d=
d=
d=
d=
so we have
d=
Answer: last option.
Step-by-step explanation:
According to the Product of powers property, you have:
As you can see, when you can add the exponents when you have powers with equal base.
Then, and do not have the same base, therefore, the exponents can't be added.
Therefore, Eli is incorrect, because he added the exponents even though the bases are not the same.
the perimeter will then just be the sum of the distances of A, B and C, namely AB + BC + CA.
