Question

Which of the expressions are equivalent to the one below? Check all thatapply.3. (2 + 6) + 4.5A. (6+2): 3+ 4.5B. 3.2 + 3.6+4.5O C.3.2 + (6 + 4): 5D. 5·4+3.(6+2

Answer 1

We have

`3\cdot(2+6)+4\cdot5=44`

For the other expressions

`(6+2)\cdot3+4\cdot5=44`
`3\cdot2+3\cdot6+4\cdot5=44`
`3\cdot2+(6+4)\cdot5=56`
`5\cdot4+3\cdot(6+2)=44`

As we can see the expressions that are equivalent are A, B, and D.

ANSWER

A, B, and D.
