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).

Answer:
the are would be 18
Step-by-step explanation:
bc 2x3=6 and then 4x3=12 so 12+6=18
Answer:
254.34 cm^2
Step-by-step explanation:
Volume of cylinder = 
We know that the diameter is 6, which means that the radius is 3 cm.
Now, it also tell us that that the height is triple the radius, this means that we multiply it by 3. Therefore, the height is 9 cm.
Now we know r = 3 cm and h = 9 cm, pi is assumed to 3.14 as well.
Substituting into the formula we will end up with 254.34 cm^2.
The slope is the same as rate of change. In a linear graph, it is the change in y over the change in x.
