Answer:
i mean math is my second favorite subject
Step-by-step explanation:
here's the answer I have in the photo and solution too
x = 8
29=7x + 5 -4x
add like terms: 29 = 3x +5
get your x variable on one side
24 = 3x
divide by 3
check!
29 = 7(8) + 5 -4(8)
29 = 56 + 5 -32
29 = 51 - 32
29 = 29
x+9
the perimeter of any polygon is the sum of all the sides
