Answer: + or - (square root of 3)/2
Step-by-step explanation:
3-4x^2=0
Add 4x^2 on both sides
3-4x^2+4x^2=0+4x^2
3=4x^2
Divide both sides by 4
4x^2/4 = 3/4
x^2 = 3/4
Since it’s a square x can be a negative number or a positive number.
x = square root (3/4) = (square root of 3)/2
x = + or - (square root of 3)/2

First, replace the numerator with the parentheses.
Second, multiply both sides by 3.
Third, multiply 2 × 3 to get 6.
Fourth, take away 15 from each side.
Fifth, simplify -6 - 15 to get -21.

Answer:
n = -21

❖ There will be 16 girls.
The relationship is x4. If we multiply 3 x 4, we get 12. What we do to one number we do to the other so 4 x 4 = 16.

Answer:
About 5043.58
Step-by-step explanation:
The standard form for an exponential decay after t time is:

Where a is the initial value, r is the rate decay, t is the time that has passed, and d is the amount of time it takes for 1 cycle.
The initial value is 9800. So a = 9800.
The quantity cuts in half. So, r = 1/2.
And it cuts in half every 6 days. For this question, we will convert this to hours. 6 days = 144 hours. So, we can let d = 144, where t will be in hours.
Therefore, our function is:

Where t is the amount of time that has passed, in hours.
Then the quantity left after 138 hours will be:

512x^3 would be the answer
