Question

50 points to the person that gets this correct:

The expression 2(l + w) represents the perimeter of a rectangle with length l and width w.

Which statement is true?
A. The variable 2 is being multiplied by (l + w).
B. There are two variables in the expression l and w.
C. (l + w) represents the product of two terms: l and w.
D. The expression is the quotient of two factors: 2 and (l + w).

Answer 1

B

Explanation:

A. The variable 2 is being multiplied by (l + w).

FALSE because "2" isn't a variable.

B. There are two variables in the expression l and w.

TRUE because variables are any letters. In this case, the letters are w and l.

C. (l + w) represents the product of two terms: l and w.

FALSE because product means multiplication when we are adding.

D. The expression is the quotient of two factors: 2 and (l + w).

FALSE quotient means divide when we are multiplying.

Best of Luck!

Answer 2

• B. There are two variables in the expression l and w.

Explanation:

Perimeter formula given

• P = 2(l + w)

Statements to confirm

A. The variable 2 is being multiplied by (l + w)

• False. 2 is not a variable, it is constant

B. There are two variables in the expression l and w.

• True

C. (l + w) represents the product of two terms: l and w.

• False. It is sum not product

D. The expression is the quotient of two factors: 2 and (l + w).

• False. It is product of two factors
