That would be 8 squared by the way. And the answer is 64

Father's age is 5 times his son's age. 4 years back the father was 9 times older than son. Find the fathers present age. a) 45 years b) 40 years c) 50 years d) 35years Cute , he's 40 & the kid is 8 Mathematic explanation: x = father's age y = son's age x = 5y x-4 = 9(y-4) x-4 = 9y-36 x = 9y-32 5y = x = 9y-32 5y = 9y-32 4y = 32 y = 8 x = 5y = 40
x-25? you dont know the value of x there for you can only write out the equation
Well the answer is... x(x-2)/2
8 x 2 = 16 sq ft
128 sq ft
16 ft * 25 ft = 16*25 = 400 sq ft.
16 x 8 = 128 sq ft
If you meant 8 ft X 8 ft, then it is 64 sq ft.
16 x 28 sq ft...
110 ft x 16 ft = 110*0.3048 metres x 16*0.3048 metres = 163.5 sq metres (approx).
64sq ft
4' X 8' = 32 sq. ft.
Area of each tile = 8/12 ft x 16/12 ft = 8/9 sq ft Area to be covered = 10 ft x 8 ft = 80 sq ft So number of tiles required = 80/ (8/9) = 80*(9/8) = 90 tiles.
four ft. x four ft. = sixteen sq. ft. example: 4ft. x 4 ft. = 16 sq. ft.
96 sq ft.
