Which of the following are true statements. the lengths 14, 24 and 26 can not be sides of a right triangle. the lengths 30, 72, and 78 can be sides of a right triangle. the lengths 14, 24 and 26 can be sides of a right triangle. the lengths 30, 72, and 78 can not be sides of a right triangle. the lengths 14, 24 and 26 can not be sides of a right triangle. the lengths 30, 72, and 78 can not be sides of a right triangle. the lengths 14, 24 and 26 can be sides of a right triangle. the lengths 30, 72, and 78 can be sides of a right triangle.

The Pythagorean Theorem would be useful here. If you have a triangle with side lengths a, b and c, and c is the longest side, then the triangle is a right triangle only if a^2 + b^2 = c^2.

Look at side lengths 14, 24 and 26. Does 14^2 + 24^2 = 26^2?

Does 196 + 576 = 676? NO.

In this particular case we do NOT have

a right triangle.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

to determine the unit cost your would divide the total cost by the number sold.
