    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
