Jacqueline records the height of her plant for three months. Her plants grow by "7 subtracted from the
product of a number and 3" inches each month.
If the pattern continues, what algebraic expression can
Jacqueline use to find the plant's height for any month?
c. Write the algebraic expression. Use the expression
height at 12 months. Work out the problem, showing
including computation and explanation.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

answer: 0.26
