The first 3 are functions as their x coordinate (number on the left side of the parentheses) is not repeated in any of the other parentheses
Are you sure you said the whole problem cuz that is impossible to answer
Answer:
You have to know the basic properties of exponents.
Jill's answer is wrong because you add the powers when there are like bases. You don't multiply.

-3+6=3
The base stays the same.
Step-by-step explanation:
(6x+4)+(4x+26)+110°=180°{straight angle}
10x+140=180°
10x=180-140
x=40/4
x=10
(6x+4)=(6×10+4)=(60+4)=64°
(4x+26)=(4×10+26)=40+26=66°
hope it helps.
