Y=3x+4 beacause the slope is m and b is the y-intercept
12 ft by 15 ft is 180 square feet. 180 square feet is 20 square yards. So take 20 multiplied by 25$ and thats how much money you have to spend to carpet Fred's room. so basically 500$
The answer is 76. Split this into two rectangles, a lower and an upper.
The upper one has dimensions of 5, 4, and 2
SO its volume is 5*4*2 or 40
The lower one has dimensions of 6, 3, and 2
So its volume is 6*3*2 or 36
40+36=76
Hope this helps<span />
