Here we are given the expression : z+ (z+6)

In this we will use the concept of like terms.

Like terms are terms whose variables (and their exponents such as the 2 in x²) are the same. In other words, terms that are "like" each other.

so here we have z and z which have same exponent which is 1.

So we can say that z and z are like terms.

So adding z and z we get 2z

so our expression becomes 2z+3

Now we may use distributive property here which is :

ab + ac = a(b+c)

where "a" is gcf of the two terms.

so in our expression 2z+6 , gcf is 2

taking 2 common out we have 2(z+3).

So answer is option c) 2(z+3).

step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
