Answer:

Correct choice is (C). 4z^5.

Step-by-step explanation:

Given expression is -3z^5-\left(-7z^5\right).

Now we need to simplify that then select the correct difference value from the given choices.

-3z^5-\left(-7z^5\right)

negative times negative is positive

=-3z^5+7z^5

Combine like terms because variable z has same exponent.

=(-3+7)z^5

=4z^5

Hence correct choice is (C). 4z^5.

Solve with Quadratics
leonid [27]

Answer:

x = 1 ± \sqrt{6}

Step-by-step explanation:

Given

2x² - 4x = 10 ( divide through by 2 )

x² - 2x = 5

Using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 1)x + 1 = 5 + 1

(x - 1)² = 6 ( take the square root of both sides )

x - 1 = ± \sqrt{6} ( add 1 to both sides )

x = 1 ± \sqrt{6} ← exact solutions

What what is the mean of the cars
tatuchka [14]
Mean is the average. to find mean, you add all the numbers and divide it by how many numbers there are.

68 + 75 + 85 + 80 + 75 + 82 = 465

There are 6 numbers. That means you have to divide 465 by 6 to get the mean.

Divide:

465 / 6 = 77.5

The answer is D. 77.5

Hope this helped☺☺
