Corresponding sides of the two triangles occur in a ratio with one another. In particular, you have the relationship

We only need the first two parts to solve for

I can’t see A-c can u take another picture
The answer to (-7)+1+4= -2
It would be elimination (C) because 7x and -7x can be eliminated into 0.
7x + 5y = 19
-7x - 2y = -16
3y = 3
3 3
y = 1
7x + 5y = 19
7(1) + 5y = 19
7 + 5y = 19
- 7 - 7
5y = 12
5 5
y = 2.4
(x, y) = (1, 2.4)
Volume= a^3 if i understand the question correctly
