Solve 6x + 13 = 31 a. 3.5 b. 108 c. 3 d. 7.3

C. 3

Step-by-step explanation:

Subtract 13 from each side

    The equation is now 6x=18

Then divide each side by 6

    The equation is now x=3

Your answer is C. 3

Step-by-step explanation:

x=  18/6  

Divide 18  by  6.

x = 3

14.29%

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.
