= -3.5 / 1
Answer:
The sides are 5,18,16
Step-by-step explanation:
To find the perimeter of a triangle, we add up all the sides
n +4n-2 + 5n-9 = 39
Combine like terms
10n -11 = 39
Add 11 to each side
10n-11+11 = 39+11
10n = 50
Divide by 10
10n/10 =50/10
n = 5
Now we need to find each side
n = 5
4n-2 = 4(5)-2 = 20-2 =18
5n-9 = 5(5) - =25-9 = 16
The sides are 5,18,16
I think it might be c, or a.
Answer:
1. f-2
2. 12z+15
Step-by-step explanation:
1. ¼(4f - 8)
1/4 * 4f - 1/4 *8
f -2
2. (-8z - 10)(-1.5)
-8z* (-1.5) - 10 * (-1.5)
12z +15
