Question

Which statements are true about the expression 8 (a + 7)? Check all that apply.

Answer 1

Answer:

Option 3)

8(a + 7) can be rewritten as 8(a) + 8(7).

Option 7)

An equivalent expression is 8a + 56

Step-by-step explanation:

We are given the following expression:

$8 (a + 7)$

We can simplify the expression by distributing 8 over (a+7).

Distributive property:

$a(b+c)\\=(a\times b) + (a\times c)\\=a(b) + a(c)\\=ab + ac$

Simplifying the expression, we get,

$8(a+7)\\=(8\times a)+(8\times 7)\\=8a + 56$

Thus, the correct options are:

Option 3)

8(a + 7) can be rewritten as 8(a) + 8(7).

Option 7)

An equivalent expression is 8a + 56
