Answer:
x= 3±sqrt(15)
Step-by-step explanation:
x^2 -6x = 6
Take the coefficient of x
-6
Divide by 2
-6/2 = -3
Square it
(-3)^2 = 9
Add this to each side
x^2 -6x+9 = 6+9
(x-3)^2 = 15
Take the square root of each side
sqrt((x-3)^2) = ±sqrt(15)
x-3 = ±sqrt(15)
Add 3 to each side
x-3+3 = 3±sqrt(15)
x= 3±sqrt(15)
Answer:
Step-by-step explanation:
We have been given that there were 32 volunteers to donate blood. Unfortunately, n of the volunteers did not meet the health requirements, so they couldn't donate.
So the number of volunteers that donated blood will be 32-n.
We are also told that the rest of the volunteers donated 470 milliliters each.
To find the units of blood donated by each of the volunteers we will divide total units of donated blood by number of volunteers, who donated the blood (32-n).
Therefore, each of the volunteers donated millimeters of blood.

Step-by-step explanation:
Answer:
5/4 =x
7/4 =y
Step-by-step explanation:
We can use proportions to solve. Put the small triangle side over the big triangle side
5 8
---------- = -------------
5+x 10
Using cross products
5*10 = 8(5+x)
Distribute
50 = 40+8x
Subtract 40 from each side
50-40 =40-40+8x
10 = 8x
Divide by 8
10/8 = 8x/8
5/4 =x
7 8
---------- = -------------
7+y 10
Using cross products
7*10 = 8(7+y)
Distribute
70 = 56+8y
Subtract 56 from each side
70-56 =56-56+8y
14 = 8y
Divide by 8
14/8 = 8y/8
7/4 =y
