Area of square base:
13 x 13 = 169
Area of triangular sides:
B x H/2
13 x 16/2 = 104
104 x 4 = because there are 4 triangular sides of the figure = 416
416 + 169 = 585in^2
590in^2
Length X Width =
2 x 7 = 14
2/9 x 7 = 44/9
14 + 44/9 = 18 8/9
He has 18 8/9 feet left to tile.
A subtracted from b means b-a
7g+11 subtracted from 12 means 12-(7g+11)=12-1(7g+11)=12-7g-11=12-11-7g=1-7g
2nd answer.
any pts in the shaded region satisfies your simultaneous equation.
Number 7 is a because line m crosses at 2 on the y axis and number 8 is a because it goes up by one half each time
