The figure is a right triangle so we can use the Pythagorean theorem to find the third side AKA the hypotenuse.

Pythagorean theorem = a² + b² = c² where A and B are the legs of the triangle and C is the hypotenuse.

39² + 80² = c²

169 + 6400 = c²

6569 = c²

Square root both sides to cancel out the squared variable.

√6569 = √(c²)

√6569 = c

The third side, the hypotenuse, is √6569 units long.

Sever21 [200]
Well it depends on the type of crayon box that she buys. For instance, some crayon boxes have a 24 pack box of crayons while others have 64 or maybe even a 16 pack box of crayons. So it all depends on what kind of box she bought.

PLEASEE HELPP!!!<br> What is the mistake in setting up the quadratic formula?
timama [110]

Answer:

First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) . See examples of using the formula to solve a variety of equations.
