Describe the error in the work shown below.
find an expression equivalent to 18 + 30.
factors of 18: 1, 2, 3, 6, 9, 18
factors of 30: 1,2,3,5, 6, 10, 15, 30
18 + 30 = 6(3 + 10)

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b

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.
