Answer:
4.5
Step-by-step explanation:
1/2 times base times height
( Area of a triangle )
1/2(3)(3)
=4.5
I think the answer is 90 degrees
Answer:
11
Step-by-step explanation:
5x+15+20=90
5x+35=90
-35 from both sides
5x=55
divide both sides by 5
x=11
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.
