3w + 8 - w = 4w - 2(w - 4)
is an identity
3w-w + 8 = 4w - 2w + 8
2w + 8 = 2w + 8
2w - 2w = 8 - 8
0 = 0
zero equal to zero implies that any value of w satisfies the statement 3w + 8 - w = 4w - 2(w - 4) hence it is an identity.

Distributive property simplify 5(3v-7)

Naddik [55]

Answer:

$15v-35$

Step-by-step explanation:

The distributive property states that $a(b+c)=a*b+a*c$ , where $a$ , $b$ , and $c$ are real numbers. In this case, $a=5$ , $b=3v$ , and $c=-7$ . Therefore, $5(3v-7)=5*3v+5*(-7)=15v-35$ . Hope this helps!
