The exterior angles = 180 - 157.5 = 22.5 degrees
the exterior angles of all polygons add up to 360 degrees
therefore the total number of sides n = 360 / 22.5 = 16
Here’s how to solve:
3x-15+-9
3x-24
Answer:
A
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 3, 8) and (x₂, y₂ ) = (0, 10) ← 2 ordered pairs from the table
m = 
= 
→ A

a)
- remove first parentheses and add: -6×[-12+26] =-6×[14]
- remove third parentheses and multiply:-6×14=-84
c)
- remove first parentheses and add:(6)×[-17+28]=6×[11]
- remove third parentheses and multiply: 6×11=66
e)
- remove first parentheses and substract:7×[-12-(6)]=7×[-12+(-6)]=7×[-18]
- multiply:7×[-18]=-126
