Answer 1

Answer:

see below

Step-by-step explanation:

4(-3 +15) = 48

4(4 + 2 + 5) = 44

4(7 + 2 + 3) = 48

4(8 + 6-2) = 48

4(-2-4 + 16) = 40

Answer 2

We are required to select all expressions equivalent to 48

All expressions are equivalent to 48 except 4(4 + 2 + 5) and 4(-2-4 + 16)

Check all options:

• 4(-3 +15)

= 4(12)

= 48

• 4(4 + 2 + 5)

= 4(11)

= 44

• 4(7 + 2 + 3)

= 4(12)

= 48

• 4(8 + 6-2)

= 4(12)

= 48

• 4(-2-4 + 16)

= 4(10)

= 40

Therefore, all expressions are equivalent to 48 except 4(4 + 2 + 5) and 4(-2-4 + 16)
