What is 4+5? pls answer

9

Step-by-step explanation:

We can split 4 up into ones: 1 + 1 + 1 + 1 = 4

Similarly, we can split 5 up into ones: 1 + 1 + 1 + 1 + 1 = 5

When we add, we're basically putting those ones together:

(1 + 1 + 1 + 1) + (1 + 1 + 1 + 1 + 1)

We can count and see that we have 9 ones. Thus, the answer is 9.

Hope this helps!

step-by-step explanation:

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)
