What is the solution of the equation?

7

Step-by-step explanation:

Restriction: x ≥ 4  why? because

            -4     -4  

2x - 5 = x² - 8x + 16

-2x +5        -2x   +5  

       0 = x² - 10x + 21

       0 = (x - 3) (x - 7)

0 = x - 3        0 = x - 7

3 = x

not valid

you divide the cost ($15) by the quantity (6) to get your questions answer. the yo-yo costs $2.50. hope this : )!

step-by-step explanation:

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
