Firstly subtract 4 from both sides

Then we are left with the the cube root of 6x +12 which equals to 8

How we do we undo a cube root you say!

We exponentiate both sides to the third power!

So now we got ride of the cube root sign and are just left with:

6x+12=8^3

6x+12= 512

Subtract 12 from both sides

And you get 6x=500

Divide by six

500/6=x

Simplify

250/3

Hope this helped!

Find AM in the parallelogram if PN =15 and AO = 6. The diagram is not to scale.
valentinak56 [21]

Answer:

6

Step-by-step explanation:

The diagonals of a parallelogram bisect each other.

The diagonals are PN and MO. The point A divides PN into 2 equal segments as well as MO into 2 equal segments.

Since AO = 6, MA should also be equal. Hence, MA (or AM) = 6.

The correct answer is AM = 6

Base of triangle exceeds the height by 4. If the area is 178.5 square inches, find the length of the base and the height of the
xxMikexx [17]
Area of a triangle:
A= (1/2)(bh)

In this problem we are given:
A= 178.5 in^{2}
b= h+4 in
h= UNKNOWN ("h")

Plug in our values into the area equation and solve for "h":
A= \frac{1}{2} bh
178.5 = \frac{1}{2} ((h+4)h) (multiply each side by 2 to get rid of the 1/2)
357 =  ((h+4)h)
357 =  h^{2} +4h
0=  h^{2} +4h -357
(357/21=17)
0= (h+21)(h-17) (solve both inequalities separately)

0= (h+21)
-21= h ( a negative height is not possible so, this answer is incorrect.)

0=(h-17)
h=17 in

Answer: base = (h+4)= (17+ 4) b= 21 in h= 17in

PLEASEEE HELP!!!!!!! Tim sells two types of pizza. He charges $10 for a cheese pizza and $15 for a pepperoni pizza. Yesterday he
Tanzania [10]

Answer:

$880

Step-by-step explanation:

This is called a system of equations!! Here's how to do it:

1. Make Equations

In this case, the equations would be

  • p+c=64 (this is saying that pepperoni pizzas plus cheese pizzas equal 64, which we got from the question.)
  • 1/3c=p (this is telling us that he sells 1 pepperonis for 1/3 cheese pizza)

2. Solve the system of equations

For this problem, we will substitute 1/3c for p. The problem becomes

  • 4/3c = 64

Then you divide by 4/3 to get p by itself:

  • p=48

Now substitute 48 for p in the first equation.

  • c=16

3. Find the money amounts

Now that you know that pepperoni pizzas equal 48, and cheese equals 16, this is easy.

  • Multiply 16*10 to get the cheese cost. ($160)
  • Multiply 15*48 to get the pepperoni cost ($720)
  • Then add those to get the total!
