Answer:
Step-by-step explanation:
square = 468 m² x² + (6+x)² = 468 [Area of a square = side²] x² + (6)² + x² + 2×6×x= 468 [(a+b)²= a²+b²+2ab] 2x² + 36 + 12x= 468 2x² + 12x + 36 - 468= 0 2x² + 12x + 36 - 432 = 0 2(x² +6x - 216)= 0 x² +6x - 216 = 0 x² +18x -12x -216 =0
I belive x=2.25 because u have to add 2x and 7x and that equals 9x then u devide 9 and 4 and that will give u 2.5
The answer must be 48 cubic inches
The answer would be A. First you have to look at the slope, which is 1/2, so it can't be C or D. Then look at where the shaded region is. The shaded region is below the line, so the y value would be less than or equal to the expression.
