Answer:
Rationalize the denominator by multiplying by the conjugate of (1 + √3), namely (1 - √3). this gives us
(1 - √3) / (1 - 3) or (1 - √3) / -2, which can be rewritten as
(-1 + √3)/2, the last answer choice.
If we are dividing than it would be answer C because 8x2=16 and 16/2=8
Answer:
55
Step-by-step explanation:
Distribute: 4x - 2 - 100 = 0
add 102 to both sides: 4x = 102
Divide both sides by 4: x = 25.5
So you want two groups that are in a ratio of 4 to 7
so 33=4x+7x
so 33=11x
so x=3
that means the groups are 4*3= 12 and 7*3=21
