The Pythagorean theorem proves a triangle is a right triangle if the square of the height  plus the square of the base equals the square of the hypotenuse ( A^2 + b^2 = c^2)
 So the answers should be:


1. Side lengths

2. a^2 + b^2 = c^2

3. is a right triangle

The Pythagoras Theorem is a^2  +b^2 = c^2 if this is true then you have a right triangle.   So I think they are looking for side lengths in the first box.

Find three consecutive even integers such that the sum of the smallest number and twice the middle number is 20 more than the la
motikmotik

Answer:

<h3>              10, 12, 14</h3>

Step-by-step explanation:

Consecutive even integers increase by 2.

x   ← an integer

2x  ← an even integer (the smallest)

2x+2   ← next even integer consecutive to 2x (the middle one)

2x+2+2=2x+4  ← the last even integer consecutive to 2x+2 (the largest)

2(2x+2)    ← twice the middle number

2x+2(2x+2)   ←  the sum of the smallest number and twice the middle

2x+4+20   ←  20 more than the largest number

2x + 2(2x + 2) = 2x + 4 + 20

2x + 4x + 4 = 2x + 24

            -4           -4

            6x = 2x + 20

         -2x       -2x

            4x = 20

            ÷2     ÷2

            2x = 10

2x+2 = 10+2 = 12

2x+4 = 10+4 = 14
