HELP ME PLEASEE i need help
sattari [20]

Answer:

x=2

Step-by-step explanation:

Add all the sides to find the perimeter

x+4 + 4x+10(x-1) = 24

Distribute

x+4+4x +10x-10 = 24

Combine like terms

15x -6 = 24

Add 6 to each side

15x-6+6 = 24+6

15x = 30

Divide each side by 15

15x/15 = 30/15

x = 2
