Evaluate each expression if a=2,6=-3,c=-1, and d=4.
2d-a

b

2(4)-(2) / -3 = -2
2•4 is 8 - 2 is 6, 6 divided by -3 is -2.

Since the triangle is a right triangle, you can use the Pythagorean Theorem to find the length of the hypotenuse.
The Pythagorean Theorem: a² + b² = c², where c is the hypotenuse of the triangle.

Plug in the leg lengths and solve.

    a² + b² = c²
    3² + 4² = c²
    9 + 16 = c²
          25 = c²
            5 = c

The length of the hypotenuse is 5 ft.
