Answer:
-191
Step-by-step explanation:
Replace variables with corresponding value.
3(3) + (-5)^2 - ((3)(-5))^2
Solve exponent.
3(3) + 25 - 225
Multiply.
9 + 25 - 225
Combine like terms.
-191
Answer:
The triangles are not similar.
Step-by-step explanation:
First, what's all the information we know?
We know we're trying to prove that triangle BAC is similar to triangle DEC.
We know AC=12 and EC =12 (proving 1 side equal).
We know angle BCA and angle DCE or equal.
However, we do not know any information further than this, and there is no postulate/theorem for AS. Therefore, the triangles are not similar.
Answer:
Step-by-step explanation:
I think the answer is number 5.
D(AB) = <span>√(6-0)^2 +(3-0)^2
d(AB) = </span><span>√36+9
d(AB) = </span><span>√45
d(AB) = 3</span><span>√5
or
d(AB) = 6.71
