I need help on understanding this concept
Sedbober [7]
So the slope formula is m= (y2-y1) /
(x2-x1). You can label -2 as x1 and 11 as y1. And the other point is x2 and y2. They you just plug it in the m= (y2-y1) /

Find the surface area of a rectangular prism measuring<br> 5 m by 8 m by 9 m.
olganol [36]
The formula of the surface area of the rectangular prism is equal:
A=2(wl+wh+lh)
where:
l - length
w - width
h - height
We have:
l = 5m
w = 8m
h = 9m
Substitute:
A=2\cdot(5\cdot8+5\cdot9+8\cdot9)=2\cdot(40+45+72)=2\cdot157=314\ m^2
