So it is how many times does 10 go into 40 which is 4 then you do 4 x 3 which is 12 so the answer to the first one is 12/40 and the second one is 42/77. hope this helped
The area would be (x+3) (4x-1) which is 4x^2 +11x -3. The perimeter is 2(x+3) plus 2(4x-1) which is 2x +6 plus 8x-2 which is 10x +4. If x=7 then the perimeter is 74 ft.
I believe <span>angle 1 is 115°

48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
54: 1, 2, 3, 6, 9, 18, 27, 54
gcf: 6
