Which expression is equivalent to (x^2 -8) - (-2x^2+4)?​
Phoenix [80]

Answer:

D) 3x^2 - 12

Step-by-step explanation:

Using PEMDAS;

There is no need to evaluate the part of the equation (x^2 - 8) because is no need to, as it is already in its simplest form.

We must evaluate the part of the equation continuing with, "- (-2x^2+4)," as it is not in its simplest form.

Evaluating "- (-2x^2+4)":

Step 1: Distributing the negative

Once distributing the negative symbol amongst the values within the parenthesis according to PEMDAS, we get "2x^2 - 4" as the product.

Step 2: Consider the rest of the equation to evaluate

Since the part of the equation is still in play here as it is a part of the original equation to be solved, we must evaluate it as a whole to get the final answer.

Thus,

x^2 -8 + 2x^2 - 4 = ___

*we can remove the parenthesis as it has no purpose, since it makes no difference.

Evaluating for the answer, we get,

x^2+2x^2 + (-8 - 4) = 3x^2 - 12

Hence, the answer is D) 3x^2 - 12.

The bonus would be worth $493,000.

3.4% = 3.4/100 = 0.034; 3.4% of 14500000 = 0.034(14500000) = 493000.

ella [17]

Answer:

Step-by-step explanation:

Is it possible for Bruce and Felicia to have used the same number of tiles? Use complete sentences to explain your reasoning.

No

5x + 2 ≠ 5x + 5

because

       2 ≠ 5

If they each used the same number of tiles, how many tiles were in each box?

6x + 2 = 5x + 17

6x - 5x + 2 - 2 = 5x - 5x + 17 - 2

        x = 15 tiles

Jerry solved the system of equations. x minus 3 y = 1. 7 x + 2 y = 7. As the first step, he decided to solve for y in the second
Reika [66]

Answer:

A. The variable x in the first equation has a coefficient of one so there will be fewer steps to the solution.

Step-by-step explanation:

Given

Equation\ 1: x - 3y = 1

Equation\ 2: 7x + 2y = 7

Required

Efficient way of solving the equations

<em>The efficient way of solving this problem is by solving for x in the first equation because it has a coefficient of 1;</em>

The evidence is shown as follows;

<em>Make x the subject of formula in equation 1</em>

x = 1 + 3y

<em>Substitute 1 + 3y for x in equation 2</em>

7x + 2y = 7

7(1 + 3y) + 2y = 7

<em>Open bracket</em>

7 + 21y + 2y = 7

7 + 23y =7

<em>Make y the subject of formula</em>

23y = 7 - 7

23y = 0

<em>Divide both sides by 23</em>

\frac{23y}{23} = \frac{0}{23}

y = 0

Recall that x = 1 + 3y

<em>Substitute 0 for y in the above expression</em>

x = 1 + 3(0)

x = 1 + 0

x = 1

Solving for y in the second equation will take more steps
