I WILL GIVE BRAIN THING

Use algebra tiles to model the expression and combine like terms. Complete the statements. x + x + x + x + 4 – 1 Combine the x tiles to get . Combine the integer tiles to get . The equivalent expression is . You can use to verify the expressions are equivalent.

Answer 1

The answer is "4x" for the first box

"3" for the second box

"4x + 3" for the third box

And "Substitution" for the last box

Answer 2

1) Combine the x tiles to get:
`\mathbf{4x}`

2) Combine integer tiles to get: 3

3) The equivalent function is:
`\mathbf{4x+3}`

4) If we Substitute any value of x both expressions will be equivalent

Explanation:

We are given expression:
`x+x+x+x++4-1\\`

We need to complete following statements.

1) Combine the x tiles to get:

`x+x+x+x\\=4x`

Combine the x tiles to get:
`\mathbf{4x}`

2) Combine integer tiles to get:

`+4-1\\=3`

Combine integer tiles to get: 3

3) The equivalent function is:

`x+x+x+x++4-1\\\\4x+3`

The equivalent function is:
`\mathbf{4x+3}`

4) If we Substitute any value of x both expressions will be equivalent

Verifying:

`x+x+x+x+4-1=4x+3\\Let\: x = 1\\1+1+1+1+4-1=4(1)+3\\4+4-1=4+3\\7=7`

So, Both expressions are equivalent.
