Solve the system of linear equations by graphing -x - y = 2
7x+y=4
Label the ordered pair on the graph.

Each of the walls of a room with square dimensions has been built with two pieces of sheetrock, a smaller one and a larger one. the length of all the smaller ones is the same and is stored in the variable small. similarly, the length of all the larger ones is the same and is stored in the variable large. write a single expression whose value is the total area of this room. do not use any method invocations.

Given the two similar triangles, how do i find the missing length? if a=4, b=5, and b'=7.5 find a'

Which expression is rational? 6. , square root two, square root 14, square root 49
