Evaluate each expression if w=2, x=3, y=5, and z=6. 3+4z

Mathematics
1 answer:
SashulF [63]3 years ago
3 0

Answer:

27

Step-by-step explanation:

The expression is 3 + 4z

First, you must know what the value of the variable "z" is.

Because the problem already tells you that z = 6, all you have to do is substitute z with 4:

3 + 4z = 3 + 4(6)

Next, solve using the Order of Operations (P.E.M.D.A.S.).

According to the Order of Operations, multiplication (M) comes before Addition (A). That means you must multiply 4 by 6 first then add the product to 3:

3 + 4(6) = 3 + 24 = <u>27</u>

Find the value of the missing coefficient in the factored form of 27f^3 + 125g^3. 27f^3+125g^3=(3f+5g)(9f^2-?fg + 25g)^2
7nadin3 [17]

Answer:

15

Step-by-step explanation:

The formula for factoring a sum of cubes is:

a^3+b^3=(a+b)(a^2-ab+b^2)

We have a=3f and b=5g here.

So a*b in this case is 3f*5g=15fg.

The ? is 15.
