Does the triangle with the side lengths of 6ft, 7ft, and 8 ft form a right triangle

  No.

Step-by-step explanation:

When the side lengths are consecutive integers, only the lengths 3, 4, and 5 will form a right triangle.

  8^2 ≠ 6^2 + 7^2 . . . . for a right triangle, the square of the hypotenuse must be the sum of the squares of the legs

  64 ≠ 36 + 49 = 85

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
