Answer:
x=18
Step-by-step explanation:
12-2/3x=x-18
12-2/3x-x=-18
12-2/3x-3/3x=-18
12-5/3x=-18
5/3x=12-(-18)
5/3x=12+18
5/3x=30
x=30/(5/3)
x=(30/1)(3/5)
x=90/5
x=18

Step-by-step explanation:
Answer:
15n^2 as it the highest expression that is common among these three.
Answer:
532 m
step-by-step explanation:
break the figure into 3 different shapes
first one is the square at the top
L • W = A
18 • 18 = 324
the next is the triangle below it
hbb/2 = A
18b16/2 = A
144
the last is the last triangle
hbb/2 = A
8b16/2 = A
64
add them together
324 + 144 + 64
532 m
