Evaluate 2x−2 for (a) x=−2 and (b) x=3. Write your answers in simplest form.

(a) x = -2

Plug in -2 for x in the equation:

2(-2) - 2

Note that when you multiply a negative number and a positive number, the product will be a negative. Also, remember to follow PEMDAS. First, multiply:

2 * -2 = -4

Next, subtract:

-4 - 2 = -6

When x = -2, your answer is -6.

(b) x = 3

Plug in 3 for x in the equation:

2(3) - 2

Remember to follow PEMDAS. First, multiply:

2 * 3 = 6

Next, subtract:

6 - 2 = 4

When x = 3, your answer is 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
