A. (2,0) (0,-3)
B. slope= 3/2
C. y= 3/2x-3
D. 3/2x+y= -3
I’m pretty sure your counting by 3’s because It’s goes 9,3 . However it might be in the negatives
Answer:
The answer to your question is 10.5 in
Step-by-step explanation:
Data
First triangle
height = x
base = 7 in
Second triangle
height = 12 in
base = 8 in
Process
1.- Use proportions to solve this problem, relates the sides of a triangle with the same sides of the other triangle.

2.- Multiply both sides by 7

3.- Simplify
x = 
4.- Result
x = 10.5 in
