QUESTION 15 A triangle has two sides that each measure x cm and it has a third
side that measures (5x 2) cm. Write an expression for its perimeter and simplify your answer

∆abc is reflected across the x-axis and translated 2 units up to give the image ∆a'b'c' with coordinates a'(1, 1), b'(2, -1), c'(2, 1). what are the coordinates of the preimage ∆abc? a. a(-1, 1), b(-2, 3), c(-2, 1) b. a(1, 1), b(2, 3), c(2, 1) c. a(1, -3), b(2, -1), c(2, -3) d. a(1, -3), b(2, -5), c(2, -3)

Select the sequences that are geometric.

Calculate the missing value. round the answer to on decimal place. start with 70, increase it by 21%, and end up with
