Question

What is the result of arranging 5 x's and 10 units into groups using parentheses?

a) (5x)(10)
b) (5x10)
c) 5(x10)
d) 5x(10)

Answer 1

The correct answer is d) 5x(10). When arranging 5 x's and 10 units into groups using parentheses, the x's should be separated from the units, resulting in 5x(10).

Step-by-step explanation:

The correct answer is d) 5x(10).

In this question, we are arranging 5 x's and 10 units into groups using parentheses. The x's represent variables, while the units represent a constant value of 10.

When arranging them into groups, we want to keep the x's together and the units together. So, we have 5 x's and 10 units. To represent this, we place the x's in one set of parentheses and the units in the other set of parentheses. Therefore, the correct arrangement is 5x(10).
