Answer:
1440x+720
Step-by-step explanation:
Expanding up the brackets, you get
160x+80.
Then you multiply the whole thing by 9.
9(160x+80)=
1440x+720
Answer:
Option C.
Step-by-step explanation:
The given table is
x f(x)
-4 0
-2 2
0 8
2 2
4 0
6 -2
A graph of a function intersect x-axis if the function contains the points whose y-coordinate is 0.
From the given table it is clear that the value of f(x) is 0 at x=-4 and x=4. It means, the continuous function intersect the x-axis at two point (-4,0) and (4,0).
Therefore, the correct option is C.
Answer:
42 units^2
Step-by-step explanation:
See diagram below
triangle on top 1/2 base * height = 1/2 * 7 x 2 = 7 units^2
triangle on bottom = 1/2 base * height = 1/2 7 x 2 = 7
rectangle in the middle = 7x4 = 28
total = 7 + 7 + 28 = 42 units^2
