Answer:
<ABC = 98.
Step-by-step explanation:
We know that the triangle is lying on a flat line, which is 180 degrees. We know that angle ABC and angle CBD are supplementary as they both use line ABD as their transversal.
Set up the equation (3 + 5x) + 82 = 180.
Solve for x, and you get 19.
Plug it back in to (3 + 5x), we get <ABC = 98.
Answer:
21 times
Step-by-step explanation:
Since the leading coefficient of the expression on the right-hand side is negative, the parabola opens downward, and has a maximum at the vertex. Therefore, we shall determine the x-coordinate of the vertex which will tell us how many times a viewer should watch a commercial for maximum effectiveness:
Therefore, a viewer would need to watch the commercial 21 times for maximum effectiveness
The correct answer here would be D. -1(3x+1)(x+5). You can find this answer by redistributing the problem.
-1(3x+1)(x+5)
-1(3x²+15x+1x+5)
-1(3x²+16x+5)
-3x²-16x-5
Using the math above, we can see that when we redistribute we get the original equation. That makes Choice D correct.
Answer:
The volume of a box with sidelines that are 20 inches is 8000 cubic inches
Step-by-step explanation:
The volume of a box with sidelines that are 20 inches can be determined by using the formula
B = S³
Where S is the length of one side
and B is the Volume
From the question, the sidelines of the box are 20 inches. That is
S = 20 inches
From
B = S³
B = (20 inches)³
B = 20 inches × 20 inches × 20 inches
B = 8000 cubic inches
Hence, the volume of a box with sidelines that are 20 inches is 8000 cubic inches.
