Answer:
x = 2 ± 2 sqrt(5)i
Step-by-step explanation:
(x – 2)^2 + 20 = 0
Subtract 20 from each side
(x – 2)^2 + 20 -20=0 -20
(x – 2)^2 =- 20
Take the square root of each side
sqrt((x – 2)^2) =±sqrt(- 20)
x-2 = ±sqrt(- 20)
We know sqrt(ab) = sqrt(a) sqrt(b)
x-2 = ±sqrt(- 1) sqrt(20)
We know the sqrt (-1) = i
x-2 = ±i sqrt(4*5)
x-2 = ±i sqrt(4) sqrt(5)
Add 2 to each side
x-2+2 = 2 ±i sqrt(4) sqrt(5)
x = 2 ±i 2 sqrt(5)
x = 2 ± 2 sqrt(5)i
you divide 12 by 25 which is 0.48 and multiply it by 48 and the answer is 48%
Answer:
Each person will get 2.7 ounces of potato salad.
Step-by-step explanation:
We are given that;
Total ounces of potato salad Greg made = 27 ounces
Number of persons to be served = 10 people
Now, we are told that each serving is the same size, thus it means each person will receive same size of potato salad.
Thus,
the amount received by each person = Total ounces of potato salad Greg made/total number of persons to be served.
So,
the amount received by each peron
= 27/10
= 2.7 ounces
Thus,
Each person will get 2.7 ounces of potato salad.
Answer:
1. -18x+6
multiply everything inside with the number outside the bracket
2. -18x-6
same as number one
3. 18x-12
same as number one
4. -18x-6
same as number one
for 5 I can't see it well but it should be similar
you just need to substitute what's outside the bracket to what Is inside the bracket
