Question

Which expression is equivalent to 2(y+4)+3(x+2x)

A. 2y+8+9x
B. 2y+4+9x
C. 2y+4+5x
D.2y+8+5x

Answer 1

`\sf \: a) \: 2y + 8 + 9x`

Explanation:

Now we have to,

→ Find the equivalent expression.

The expression is,

→ 2(y + 4) + 3(x + 2x)

Let's find the equivalent expression,

→ 2(y + 4) + 3(x + 2x)

→ 2(y + 4) + 3(3x)

→ 2(y) + 2(4) + 9x

→ 2y + 8 + 9x

→ 9x + 2y + 8

Hence, the option (a) is correct.

Answer 2

`\huge\boxed{\sf 2y + 8 + 9x}`

Explanation:

Given expression:

= 2(y + 4) + 3(x + 2x)

Combine like terms

= 2(y + 4) + 3(3x)

Distribute 2 to (y + 4) and 3 to 3x

= 2y + 8 + 9x
