Part A: Describe the two factors in this expression. (4 points) The factors are (1) the constant coefficient 9 and (2) the binomial (7+2x).
Part B: How many terms are in each factor of this expression? (4 points) The first factor (multiplicand), 9, has one term. The second factor (multiplicand), (7+2x), has two terms (and is thus called a binomial).
Part C: What is the coefficient of the variable term? (2 points) The only such coefficient is 2.
Answer: 0.18 is your answer
Step-by-step explanation:
Okay, so basically we have:
w as width; and 6+w as length
Perimeter=2w+2l
just substitute it with the values of width and length
P=2w+2(6+w)
P=2w+12+2w
P=4w+12
So, the answer is letter B.
