Answer 1

The number 65−−√ belongs to the subset of real numbers.

Answer 2

Which property is illustrated by the following statement? 2y+5=5+2y

Answer 3

The property that is illustrated by the statement 2y+5=5+2y is the commutative property of addition.

The commutative property of addition states that for any two real numbers a and b, the sum is the same regardless of the order of the terms. In other words, a + b = b + a.

In this case, we have 2y + 5 = 5 + 2y. Here, the terms 2y and 5 are being added in different orders, but the result is the same. This demonstrates the commutative property of addition.

Answer 4

Which word phrase can you use to represent the algebraic expression 12x

Answer 5

The word phrase that can represent the algebraic expression 12x is "twelve times x" or "the product of twelve and x".

Answer 6

which sum or difference is equivalent to the following expression? 4(x+3)

Answer 7

The expression 4(x+3) can be simplified by distributing the 4 to both terms inside the parentheses.

4(x+3) = 4*x + 4*3 = 4x + 12

Therefore, the equivalent sum or difference is 4x + 12.
