Hello!
We have the following expression:

Let's multiply and simplify it, look:

We multiply a*a*a, so we can rewrite it as a³. The same with b*b as b².
So, the answer in the simplified form is:
6a³ + 4b²
Answer:
Graph One.
Step-by-step explanation:
See below. The graph is in a straight line, also known as linear. The other graphs are not. Also, if you look at the range (y) of the tables, you can see the increase is linear as it is increasing by .5 (1/2) everytime.
Answer:
180°
Step-by-step explanation:
Angles that are called straight angles make up a straight line.
A straight line measures 180°.
So, angles on a straight line make up 180°.
Hope this helps.
