Answer:
Step-by-step explanation:
ok so, we know they washed 34.
x-5=Trucks washed [19.5-5=(14.5)]
x=cars washed (19.5)
x+x-5=34
2x-5=34
+5 +5
2x=39
divide 2 both sides
x=19.5
To check work: 19.5+14.5=34!

Side = 8m
He increases length by 2m and reduces width by 2m
(a.) New dimensions will be -
Length = 10m and Width = 6m
(b.) Area = length x breadth (or width)
here we will use the special product (x+y) (x-y)
length = (x+y) and width = (x-y)
area = (8+2) x (8-2)
8^(2) - 2^(2)
= 60
The answer is 4120000
I hope that helped
