Answer:
x = 26, 16
Step-by-step explanation:
( x-21) ^2 = 25
Take the square root of each side
sqrt(( x-21) ^2) = ±sqrt(25)
x-21 = ±5
Add 21 to each side
x-21+21 = 21±5
x = 21±5
x = 21+5 and x = 21-5
x = 26, 16

Answer:
The distance between two points ( -1,1) and (2,-4) is:
or d = 5.8 units.
Step-by-step explanation:
Given the points
Finding the distance between (-1, 1) and (2, -4) using the formula
![d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%5Cleft%28x_2-x_1%5Cright%29%5E2%2B%5Cleft%28y_2-y_1%5Cright%29%5E2%7D)
substitute (x₁, y₁) = (-1, 1) and (x₂, y₂) = (2, -4)
![=\sqrt{\left(2-\left(-1\right)\right)^2+\left(-4-1\right)^2}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B%5Cleft%282-%5Cleft%28-1%5Cright%29%5Cright%29%5E2%2B%5Cleft%28-4-1%5Cright%29%5E2%7D)
![=\sqrt{\left(2+1\right)^2+\left(-4-1\right)^2}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B%5Cleft%282%2B1%5Cright%29%5E2%2B%5Cleft%28-4-1%5Cright%29%5E2%7D)
![=\sqrt{3^2+5^2}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B3%5E2%2B5%5E2%7D)
![=\sqrt{9+25}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B9%2B25%7D)

Therefore, the distance between two points ( -1,1) and (2,-4) is:
or d = 5.8 units.
Well if you add all the numbers together, the total is 14. So 4/14 chance of pulling out a red marble.
He can use addition by adding 0.44 and 1.224 together to see how much Vitamin B-12 (so far he has 1.664 in all.) he has right now. then he needs to subtract that amount (1.664) of B-12 he has from the amount of vitamin B-12 (2.4) he needs. That'll be 0.736 of vitamin B-12 he needs to reach the amount of B-12 he needs.
