Look at this expression, and complete the statements. 3x + 2(x + 2) + 4 In the first term, 3 is .a coefficient, a constant, an constant, or a variable. In the second term, (x + 2) is .a coefficient, a constant, an constant, or a factor. In the last term, 4 is .a coefficient, a constant, an constant, or a variable. i'm giving 11 points for this question. and a brainliest.

3 is a constant

(x+2) is a factor

4 is a constant

3 is a constant

(x+2) is a factor

4 is a constant

answer: when you burn wood, the carbon reacts with the oxygen in the air to create ash and smoke. that is a permanent change you cannot undo that.

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
