Answer:
There are 21 ways to choose the first person, 20 ways to choose the second, 19 ways for the third and 18 ways for the fourth so the answer is 21 * 20 * 19 * 18 = 143640.
Answer:
NONE OF THE ABOVE!!
Step-by-step explanation:
A regular polygon is equilateral and equiangular, and also, can be inscribed into a circle. The polygon shown doesn't meet any of these conditions.
<span>Part A: The coefficients are 20 and 9 and variables in the expression are x and y.
</span><span>Part B: The number of terms are two in the expression, they are 20x and 9y,as they are separated by an addition sign.
</span><span>Part C: 9y term in the expression shows the total earned from trimming hedges.</span>
slope = m = (y2 - y1)/(x2 - x1)
(y2 - y1)/(x2 - x1) = m
(-1 - 1)/(-1 - x) = 2/7
-2/(-1 - x) = 2/7
2/(x + 1) = 2/7
1/(x + 1) = 1/7
x + 1 = 7
x = 6
Answer: x = 6
