Answer:
10x+5
Step-by-step explanation:
You add or subtract 5x by -25x by 30x to get 10x. However, then you add 6-5+4 which is 5.
Perimeter of rectangle = 2(l+w)
let. width = x, length = x+12
So, 100 = 2(x+x+12)
100=2(2x+12)
100=4x+24
4x=76
x=19, y=19+12 = 31
So, Length = 31 m & Width = 19 m
Let nails 7/pound=N1
nails 3/pound=N2
let N1=x
N2=6
then total=x+6
7x+6*3=(x+6)*4
7x+18=4x+24
3x=6
x=2
so 2 pounds on Nails costing 7/pound must be added
