Express as a sum: 15-7
Please show work I'm confused on how you can express it as a SUM...
Thank you!

The triangles in the diagram are congruent. if mzf = 40°, mza = 80°, and mzg = 60°, what is mzb?

Which number completes the system of linear inequalities represented by the graph? y> 2x – 2 and x + 4y 2 et 2 3 4

Show your workcan a right triangle have this sides? *how to prove it without using the pythagorean theorema*
