Question

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.

Match the expressions to their verbal descriptions. Assume that all variables represent integer values and that none are equal to each other.

Answer 1

Replace key words with variables, numbers, and operations. More than is addition, product is multiplication, and decreased by is subtraction. The constants are 1, 7, and 5. The expression is 1 + 7n – 5. To evaluate the expression, substitute 6 in for the variable, and then use order of operations to simplify. The value when n = 6 is 38.

Explanation:

Answer 2

First expression ⇒ m + 3(m - 11)²

Second expression ⇒ m(-8m)

Third Expression ⇒ -3mn²

Fourth Expression ⇒ m - 7mn

Explanation:

* The sum of m and a n term depending on m

m added to the term 3(m - 11)²

* The product of m and a multiple of m

m multiplying by its multiple (-8m)

* The product of m and a factor not depending on m

m multiplying by (-3n²) which is a factor not depending on m

* The difference between m and a factor depending on m

(-7mn) is a factor depending on m and subtracted from m
