Answer:
the answer is A
Step-by-step explanation:
10C6 = 10! / (6! * 4!) = 10 * 9 * 8 * 7 / 4! = 5040/24 = 210
8x+4
4(2x+1)=8x+4
=1
(-2-√3)(-2+√3)
=-2(-2+√3)-√3(-2+√3)
=4-2√3+2√3-√9
=4-3
a = 29
u = 12
32 + 7u + 9 + 2a - 3 = 3a + 7u + 9
32 + 2a - 3 = 3a
3(29) + 7u + 9 = 180
7u = 180 - 96
7u = 84
Setting the equations equal to each other.
