Matthew gets on a Ferris wheel at the bottom of the wheel, which is 5 feet above the ground. After 40 seconds, he is at the top of the wheel, 65 feet high.

Step-by-step explanation:

Givens

So, to know the height of the wheel, we just need to subtract distances.

Therefore, the height of the wheel is 60 feet.

The image attached shows the problem.

Step-by-step explanation:

Expressions of the form (a +b)(a +b) will result in a perfect square trinomial, because both binomial factors are identical.

Expressions of the form (a +b)(a -b) will result in a difference of squares.

Match the offered choices to either one of these forms, and they will be included in the answer set.

  (5x + 3)(5x - 3) -- difference of squares

  (7x + 4)(7x + 4) -- perfect square

  (2x + 1)(x + 2) -- nothing special

  (4x-6)(x + 8) -- nothing special

  (x - 9)(x - 9) -- perfect square

  (-3x-6)(-3x+6) -- difference of squares
