Ms. wilson draws a model of the factorization of a polynomial with integer factors. her model is partially complete. which equation is represented by ms. wilson’s model? n2 3n 40 = (n – 8)(n – 5) n2 13n 40 = (n 8)(n 5) n2 40n 13 = (n 8)(n 5) n2 40n 3 = (n – 8)(n – 5)

the correct question in the attached figure

We proceed to analyze each case

case a)

Expand the right side and compare with the left side

so

is not equal to

therefore

case a) is not the equation represented by ms. wilson’s model

case b)

Expand the right side and compare with the left side

so

is equal to

therefore

case b) is the equation represented by ms. wilson’s model

case c)

Expand the right side and compare with the left side

so

is not equal to

therefore

case c) is not the equation represented by ms. wilson’s model

case d)

Expand the right side and compare with the left side

so

is not equal to

therefore

case d) is not the equation represented by ms. wilson’s model

therefore

the answer is the case b)

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of
