Answer:
D(x) = 3x
Step-by-step explanation:
Micah travels at a rate of 'x' feet over a specific period.
Linda travels at a rate of '2x' feet over that same period.
Since they are walking in opposite directions, the total distance they have walked towards one another (D) can be determined by adding both distances:

The expression that describes the number of feet they have walked toward one another is D(x) = 3x.

Answer:
108 - 30x - 116x² - 18x³
Step-by-step explanation:
We have to get the value of - (2x + 12) (9x² + 4x - 9)
Now, using the distributive property of multiplication we get
- (2x + 12) (9x² + 4x - 9)
= -[2x (9x² + 4x - 9) + 12 (9x² + 4x - 9)]
= -[(18x³ + 8x² - 18x) + (108x² + 48x - 108)]
= -[18x³ + 116x² + 30x - 108]
= 108 - 30x - 116x² - 18x³ (Answer)

You will find the area of the semicircle by finding the area of the circle with a radius of 8.5 mm and the dividing it by 2.
A = pi x r^2
3.14 x 8.5^2
A = 226.865 square mm
226.865/2
113.43
The approximate area of the semi circle is 113.43 mm².
