You place the following shapes in a bag: 5 circles,3 triangles,7 squares and 5 rectangles. if you reach into the bag and grab a shape, what is the probability you will grab a circle?

25% chance

Step-by-step explanation:

5 + 3 + 7 + 5 = 20

5/20 equals 1/4 or 25%

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
