Step-by-step explanation:
Here, we'll need to multiply these two values together. I'll use the expansion formula, which goes as follows:


Lets apply this to the following equation:



- Remove parenthesis and add.

Answer:
x^2+10x+21
The value would be 0.95454545454 (well if you put it in a calculator then this would be your answer)
Answer:
1
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(2-8)/(-3-3)
m=-6/-6
m=1
Step-by-step explanation:
step 1. 1-12/20 = 1.6
step 2. 1.6 = 160%.
