Answer:

Number 1 can form a right triangle. Numbers 2 & 3 cannot.

Step-by-step explanation:

To check if the sides are a right triangle, check if the sum of the squares of the two smaller sides equals the length of the square of the longest side. In other words, do the Pythagorean Theorem.

5² + 12² = 13²

25 + 144 = 169

169 = 169

<u><em>They are equal therefore Number 1 can form a right triangle.</em></u>

5² + 7² = 9²

25 + 49 = 81

74 = 81

<em>They are not equal, therefore Number 2 can't form a right triangle.</em>

<em />

10² + 12² = 30²

100 + 144 = 900

244 = 900

<em>They are not equal, therefore Number 3 can't form a right triangle.</em>

Answer:

The equation is: $\frac{x-7}{5} = 13$ and the number is 72.

Let x be the required number then

"A number decreased by 7"

$x-7$
