Positive infinity and negative infinity
Answer:
The solutions are given below:
Step-by-step explanation:
x(x-3)+4(x²+2)
= x²-3x+4x²+8
= x²+4x²+8-3x
= 5x²+8-3x
2(a+5)-3(a+7)
= 2a+10-3a-21
= 2a-3a+10-21
= -a-11
xy(x²yz-xy²z+xyz²)
= x³y²z-x²y³z+x²y²z²
-4(a²-2a+8)
= -4a²+8a-32

Answer:
<u>1260 degrees (1260°)</u>
Step-by-step explanation:
<u>Formula to Find Sum of Interior Angles of a Polygon</u>
- 180 (n - 2)
- n is the <u>number of sides</u> of the polygon
<u>Nonagon (9-sided polygon)</u>
- 180 (9 - 2)
- 180 × 7
- <u>1260 degrees (1260°)</u>
25 + 100i is correct because -5 squared is 25 and the the square root of -100 is 100i or 10i in its simplest form.
There are 2² butterflies.
Or simply 2²
