Which property justifies the following equation 7 [6+5+(-6)=7 [6+(-6)+5]

Given f(t) = 282 - 53 +1, determine the function value f(2). do not include f(z) = in your answer

Tell me how you got the it use the figures to answer questions 1and 2. in each diagram, line k is parallel to line l, and line t intersects lines. 1. based on the diagrams, what is the value of x? 2. how would you verify your answer for x?

What is the answer to this question? i'm a bit stumped. also how do i do it? 5(x - 4) = 2(x + 5)
