Use the distribution property to expand 7(8x - 2y) - 5

1. are the triangles similar and if so why? what is the value of x? show your work.

List x1, x2, x3, x4 where xi is the left endpoint of the four equal intervals used to estimate the area under the curve of f(x) between x = 4 and x = 6. a 4, 4.5, 5, 5.5 b 4.5, 5, 5.5, 6 c 4.25, 4.75, 5.25, 5.75 d 4, 4.2, 5.4, 6

What is the missing reason in the proof? segment addition congruent segments theorem transitive property of equality subtraction property of equality?
