The short sides of a rectangle are 2 inches. the long sides of the same rectangle are three less than an unknown number of inches.

suppose the area of this rectangle is less than 12 square inches. which of the following numbers could be the value of the unknown number? select all that apply.

a. 2 inches

b. 4 inches

c. 6 inches

d. 8 inches

e. 10 inches

plz !

A,B,C,D

Step-by-step explanation:

Mark the unknown number as x

Now the long side is x-3 inches

S=long side*short side=(x-3)*2=2x-6 square inches

S < 12 so

2x-6 < 12

2x < 12+6

2x<18

x<9

2<4<6<8<9

4

step-by-step 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
