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.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )
