16x - 3 + 5x + 2 = 72
21x - 1 = 72
21x = 72+1
21x = 73
x = 73/21
x ≈ 3.48

Distance from Diego's house to the restaurant:
16x - 3 = 16 * 3.48 - 3 ≈ 52.6 miles

Distance from Anya's house to the restaurant:
5x + 2 = 5 * 3.48 + 2 ≈ 19.4 miles

52.6 ≠ 19.4 ⇒ <span>Diego was wrong.</span>

The lengths of two sides of a right triangle are 12 inches and 15 inches. What is the difference between the two possible length

andrew11 [14]

we know that

In a right triangle

Applying the Pythagorean Theorem

$c^{2} =a^{2} +b^{2}$

where

a and b are the legs of the triangle

c is the hypotenuse of the triangle

Step N $1$

<u>Assume that the third side is a leg</u>

In this case we have

$a=12\ in\\c=15\ in\\ b=?$

$c^{2} =a^{2} +b^{2}$

Solve for b

$b^{2}=c^{2} -a^{2}$

substitute the values

$b^{2}=15^{2}-12^{2}$

$b^{2}=81$

$b=9\ in$

Step N $2$

<u>Assume that the third side is the hypotenuse</u>

In this case we have

$a=12\ in\\b=15\ in\\ c=?$

$c^{2} =a^{2} +b^{2}$

substitute the values

$c^{2}=12^{2}+15^{2}$

$c^{2}=369$

$c=19.2\ in$

Step N $3$

<u>Find the difference of the third sides</u>

$19.2\ in-9\ in=10.2\ in$

therefore

<u>the answer is</u>

$10.2\ in$
