Answer:
24
Step-by-step explanation:
the area of white board = (2×12) ×4 = 96 sq in.
the area of post-it = 2×2 = 4 sq in
so, numbers of post-it = 96/4 = 24
Answer:
The area is 3.9375 cubic ft, so yes, the area will greater than 3 and 1/2 ft.

Step-by-step explanation:
The slope-intercept form of a line is:
y=mx+b, where m=slope and b=y-intercept (value of y when x=0)
First you must find the slope, or m value.
m=(y2-y1)/(x2-x1), which is the change in y divided by the change in x. In this case:
m=(5--3)/(-4--1)
m=(5+3)/(-4+1)
m=8/-3
m=-8/3
So far our line is:
y=-8x/3+b, we can now solve for the y-intercept, or b, using any point on the line, I'll use (-4,5):
5=-8(-4)/3+b
5=32/3+b
15/3=32/3+b
15/3-32/3=b
-17/3=b
So now we know the value for both terms in our line:
y=(-8x-17)/3
