4(9)(2)
4(90) + 4(2)
4(90)(2)
4(90) + 2

Answer 1

Answer:

4(90) + 4(2)

Explanation:

The given expression is 4(92)

This can be expressed as

This can also be expressed as

Using the distributive law of multiplication and additon,

a*(b+c) = a*b + a*c

In this case a=4

b=90 and c = 2

So the equivalent expression is

But this is the same as option 2 in the list of given options.

Hence the equivalent expression is 4(90) + 4(2)

Explanation:

Answer 2

4(90) + 4(2)

Explanation:

The given expression is 4(92)

This can be expressed as
`\[4*92\]`

This can also be expressed as
`\[4*(90+2)\]`

Using the distributive law of multiplication and additon,

a*(b+c) = a*b + a*c

In this case a=4

b=90 and c = 2

So the equivalent expression is
`\[4*(90)+4*(2)\]`

But this is the same as option 2 in the list of given options.

Hence the equivalent expression is 4(90) + 4(2)
