PLZZZ Help With This Its Pretty Simple!

Answers

Answer 1

Answer:

It should be D, [tex]x^4 - 2x^3 + 7x^2 -12x - 4[/tex]

Step-by-step explanation:

Since, the equation given in the question is the factored form of the equation D. It can be solved using FOIL (First Outside Inside Last):

x * x³ = [tex]x^{4[/tex]

x * 7x = 7x²

x * 2 = 2x

-2 * x³ = -2x³

-2 * 7x = -14x

-2 * 2 = -4

This all would add up to ⇒ [tex]x^{4}[/tex] - 2x³ + 7x² + (-14x + 2x) -4

Simplifying the parenthesis further would give the option D as the answer.

You can see the picture for the steps but I’m sure the answer is -72

Answer:

x = -72

Step-by-step explanation:

Using algebra:

⇒ [tex]-\frac{x}{8} -11 = 2[/tex]  (First add 11 to both sides of "=")

⇒ [tex]-\frac{x}{8} =9 (11 + -2)[/tex] (The multiply both sides by "8")

⇒ [tex]-x = 9*8[/tex] (Lastly the answer is 72 when x-value is negative, so when x-value will be positive the answer will be opposite of 72 which is -72)

⇒ [tex]x = -72[/tex]

Hope this helped, Good Luck!

Here is to my last q

Answers

Mode: value that occurs most
Mean: average (add all values then divide by the amount of number)
Median: middle number

Mode: 80 (appears the most)
Mean: 95 + 80 + 80 + 85 + 80 + 85 + 90 = 595/7 = 85, the mean is 85
Median first put them in order
80, 80, 80, 85, 85, 90, 95
The median is the middle which is 85

Which statement matches?

Solution: D

Answer: D (Mean is 85)

Explanation:

"The list below shows the quiz scores for a group of students.

95, 80, 80, 85, 80, 85, 90"

The choices talk about median and mode so we find those first:

Median: find by taking which is the middle number when the data is from low to highest

1) rearrange them from low to high

80, 80, 80, 85, 85, 90, 95

2) find middle number

80, 80, 80, 85, 85, 90, 95

The median is 85

Mean: mean is the average of all numbers. Find by adding numbers and dividing by amount of numbers

1) add 80, 80, 80, 85, 85, 90, 95 and get 595

2) There are 7 total numbers so do 595/7 = 85

The mean is 85

D is the correct answer

why?

A is wrong because they are 85 not 80

B is wrong because it is 85 not 80

C is wrong because it is 85 not 80

D is right because it is 85!
