Answer:
answer is 12
Step-by-step explanation:
because 5×4=20
so u have to multiply 4 and three
3×4=12
and u can reduce it to
6/10 and reduce it again to
3/5
“Average rate of change” is the fancy way to say “slope.”
Sketch a graph and put two points with the same y-value, say (2,5) and (7,5).
How much rise is there between those two points? Since they have the same y-value there is no rise at all. You have a horizontal line.
The slope of a horizontal line is 0.
2(x + 1) - 3x = 0
2x + 2 - 3x = 0
-x + 2 = 0
-x = -2
Divide -1 on both sides
x = 2
Area = pi x radius squared... so
a = pi x 10in^2
a = 314.159
5 feet = 60 inches
