Ms. Wilson draws a model of the factorization of a polynomial with integer factors. Her model is partially complete
5n
Which equation is represented by Ms. Wilson's model?
m+ 3 + 40 = (n-)(n-5)
1? +13 + 40 = (n +8)(n+ 5)
m2 + 40 + 13 = (n+8)(n+5)
12.40n + 3 = (n-3)(n-5)

B) n^2 + 13n + 40 = (n+8) (n+5)

Step-by-step explanation:

Break it down:

(n+8) (n+5) = n^2 + 5n + 8n + 40

Combine like terms = n^2 + 13n + 40

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)

(3x-8) or (3x+8)
