<u>Use the ratio of corresponding sides of similar triangles:</u>
- 81 / x = x / 144
- x² = 81*144
- x =

- x = 9*12
- x = 108
Answer:
x = -5
Step-by-step explanation:
15*x = -75

Answer:
Graph is option A
Step-by-step explanation:
3x + 5y = –15
To graph the equation , we need to get y alone

Subtract 3x on both sides

Divide whole equation by 5

To graph this equation , we need to make a table
Plug in some number for x and find out y
x 
0 -3
-5 0
Two points on the graph is (-5,0) and (0,-3)
Graph is option A
