Xavier Designs has the logo shown below on their office door. The logo has two smaller congruent triangles that are similar to two larger congruent triangles.

If w = 7.5 inches, x = 10 inches, y = 3 inches, a = 12 inches, and b = 12 inches, what is the area of the space around the triangles on the logo?

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

Daniel expanded the expression as shown below -2(-8x-4y+3/4)=-10x-8y-11/4 what errors did he make? check all that apply

Asap! i'm not good math and i'm lost.
