19) 20)
The expression would be:
3x+4x+5x
If x=8, the perimeter would be:
3(8)+4(8)+5(8)
24+32+40
=96 feet
21) 22)
The expression would be:
x+14+5+7+5.5+2x
If x=10.5, the perimeter would be:
10.5+14+5+7+5.5+2(10.5)
10.5+14+5+7+5.5+21
=63 feet
Hope this helps.

What is the essential question? We need more details please :)
Answer:
2x + 5y = -15 OR 2x + 5y + 15 = 0 Not sure they want it equal to zero
Step-by-step explanation:
y + 7 = -2/5(x - 10)
y + 7 = -2/5 x + 4
2/5x + y =-3
5(2/5 x + y = - 3)
2x + 5y = - 15
OR
2x + 5y + 15 = 0
