Answer:
12 would be the distance between the two points
Step-by-step explanation:
The y-coordinates are the same, so the length of this horizontal line segment is the difference between the x-coordinates.
Length = 7 - (-5) = 12 units
x^n*x^3=x^13
x^(n+3)=x^13
n+3=13
n=10
12 CD
11 cu
17 Br
15 p
b.group 18
Answer: da vinkiy
3a) Answer: 84 degrees
3x + 2(x+20)= 180 (total sum of angles in a triangle is 180 degrees)
5x+40 = 180
5x = 140
x= 28
3x= 28 x 3
= 84
