Answer:
x= 13/2
Step-by-step explanation:
multiply 4x4+4x3-9x2-x+2=x-1
calculate 16+12-18-x+2=x-1
move the terms 12-x=x-1
collect like terms calculate -x-x=-1-12
divide both sides -2x=-13
solution x=13/2
18/4=x/10
The correct answer would be 4 x 10^4 sq ft.
40m
0.2/1=8/x
cross multiply
8*1=0.2x
8=0.2x
8/0.2=x
x=40
