Atextbook has a length of 6 inches, a height of y inches, and a width of x inches. if the length of the diagonal of the front cover is 8 inches and the length of the diagonal of the width is 7 inches, find the values of x and y.

x = 2√7, y = √21

Step-by-step explanation:

The textbook has right angles, so we can use Pythagorean theorem to find the missing lengths.

For the triangle on top of the textbook:

c² = a² + b²

8² = 6² + x²

64 = 36 + x²

28 = x²

x = √28

x = 2√7

For the triangle on the side of the textbook:

c² = a² + b²

7² = x² + y²

49 = 28 + y²

21 = y²

y = √21

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
