Ms. wilson draws a model of the factorization of a polynomial with integer factors. her model is partially complete. a 2-column
lana [24]

The equation represented by Ms. Wilson's model is n² + 13n + 40 = (n + 8)(n + 5)

<h3>How to determine the equation of the model?</h3>

The partially completed model is given as:

    |  n

    |  n²

5   | 5n  |  40

By dividing the rows and columns, the complete model is:

    |  n    | 8

n   |  n²  |  8n

5   | 5n  |  40

Add the cells, and multiply the leading  row and columns

n² + 8n + 5n + 40 = (n + 8)(n + 5)

This gives

n² + 13n + 40 = (n + 8)(n + 5)

Hence, the equation represented by Ms. Wilson's model is n² + 13n + 40 = (n + 8)(n + 5)

A person's intelligence quotient (i) is found by dividing mental age (m), as indicated by standard tests, by chronological age (
Elan Coil [88]

9.6 \leqslant m \leqslant 14.4
i = (100m)/c
lowest i = 80, highest i = 120
c = 12
this will result in 2 equations, one will be the lowest (solving m when i = 80), and the highest (solving m when i = 120)
solve m when i = 80:
i = (100m)/c
80 = (100m)/12
80×12 = 100m
960 = 100m
960/100 = m
9.6 = m
solve m when i = 120:
i = (100m)/c
120 = (100m)/12
120×12 = 100m
1440 = 100m
1440/100 = m
14.4 = m
therefore,
9.6 \leqslant m \leqslant 14.4
