Answer:
The formation of the equation is odd, but I assume it's supposed to be:
4k - 10k = -8k
-6k = -8k
-6k + 8k = -8k + 8k
2k = 0
= 
k = 0
B..............
c>=3 and n<0 and p<=(9-3 c)/n
Rectangle:
length = 12
width = 6
area of rectangle = length times width = 12 x 6 = 72
area of circle = pi r^2 = 3.14 (6)^2 = 113.1
1/2 circle = 113.1 / 2 = 56.55
<span>the area of the shaded of the shaded region = 72 - 56.55 = 15.45
</span>
answer
15.45
Answer:
40
Step-by-step explanation:
The two angles form a right angle
A right angle has a measure of 90 degrees meaning that the sum of the two angles is 90
a + 50 = 90
90 - 50 = 40
Thus, a = 40
