216 square units
432 x 12 inch x 12 inch bricks for an area 18 feet x 24 feet
area = width times height x = height x-12 = width x (x-12) = x^2 - 12X = 400 x^2 - 12X - 400 = 0 solve for x using quadratic formula X = (12 + SQRT(144 + 1600)) divided by 2 x = 26.88 = height width = x -12 = 14.88
You need to be careful in how you write such questions as it is important to know if you mean: x - 12/2 = 18 or (x-12)/2 = 18 If x - 12/2 = 18 then x = 18 + 12/2 x = 18 + 6 x = 24 If (x-12)/2 = 18 then x - 12 = 18 * 2 x - 12 = 36 x = 36 + 12 x = 48
216 square feet. (12 x 18 = 216)
x + 12 = 18 Therefore, x = 18 - 12 x = 6
The formula for the area (A) of a triangle is A = 1/2 base x altitude (or vertical height). 18 = 1/2 x base x 12 : base = 2 x 18 ÷ 12 = 3 : The base is 3 in long.
If you fill it to the brim, it would be 55 x 12 x 18 = 11880 cubic feet
If you mean -x +x/3 = 12 then the value of x is -18 Check: --18 +(-18/3) = 12
12 x 18 = (12 x 10) + (12 x 8)
18" x 18" = 1.5ft x 1.5 ft = 2.25 sq ft 12 ft x 12 ft = 144 sq ft So number of paver required = 144/2.25 = 64
If you mean 4-x = 18 then the value of x is -12 because 4--12 = 18
18 inches = 18/12 ft 14 inches = 14/12 ft (18/12) x (14/12) = (18 x 14) / (12 x 12) = 252/144 = 1.75 ft2
