Step-by-step explanation:
-16 + 3n = - 8 - 5n
Bringing like terms on one side
3n + 5n = - 8 + 16
8n = 8
n = 8/8
N = 1

Answer:
w = x = 36
Step-by-step explanation:
In the largest triangle, the longest side is x
The shortest side = 18
In the smaller triangle the longest side is 6
The shortest side is 3
You can set up a ratio
x/18 = 6/3 Divide the right side by 3
x/18 = 2 Multiply both sides by 18
18 *x / 18 = 2 * 18
x = 36
Answer:
xy = - 27
Step-by-step explanation:
Note that
(x - y)² = x² - 2xy + y² ← substitute given values, that is
9² = 27 - 2xy
81 = 27 - 2xy ( subtract 27 from both sides )
54 = - 2xy (divide both sides by - 2 )
- 27 = xy
