23. What are all the factors of 15? A 1, 3,5
B 1, 3, 5, 10
C 1, 2, 3, 5, 10
D 1, 3, 5, 15

Help

D. 1, 3, 5, 15

Step-by-step explanation:

Factors are numbers that divide another number evenly, with no remainders.

15 ÷ 1 = 15

15 ÷ 3 = 5

15 ÷ 5 = 3

15 ÷ 10 = 1.5

15 ÷ 2 = 7.5

15 ÷ 15 = 1

The numbers that 15 divide evenly into are 1, 3, 5, and 15.

Hope that helps.

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base

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)
