Can anyone please help me with 1,2,&,3 ?

Answers

Answer 1

Answer:

Okay, lets start with number 1.

$(x+3)^(3)$ is also equal to (x+3)(x+3)(x+3)

If you take the first two ones and multiple them out it ends up with $x^(2) + 3x +3x + 9$ or also know as $x^(2) + 6x + 9$

You see to multiply them you take the first number in the first group of parenthesis and use the distributive property on the second equation, then you do the same this but with the second number in the first equation.

So once you have $(x^(2) + 6x + 9)$ you multiply it with your remaining (x + 3) using the distributive property to get $x^3 + 9x^2 + 27x + 27$

I hope this helps you get the answers for the other two.

Answer 2

Answer: (x+3)^3 = x^3+9x^2+27x+27

(x+2)(x-2)(x^2+4) = x^4-16

(x-2)^2+1 = x^2-4x+5

What is the slope of the line that passes through the points (5,6) and (5,9)?

Answers

Answer:

undefined

Step-by-step explanation:

The slope of a line given two points is given by

m = (y2-y1)/(x2-x1)

= (9-6)/(5-5)

= 3/0

This slope is undefined

Answer: no slope

Step-by-step explanation: To solve this problem, we would usually use our slope formula but there is a faster way to solve this problem.

Notice that each ordered pair has the same x-coordinate which is 5.

Whenever you have the same x-coordinates, the line will have no slope.

That's because you must subtract the second y minus the first y over the second x minus the first x and you will end up with a denominator of 0 and you can't divide by 0.

Since any number divided by 0 is undefined, this line would be too.

If a line has no slope, it means that we cannot describe its slope using a number because the line is vertical and its slope is undefined.

Percent of change 25 points to 50 points

Answers

percent change
first find change
then find as a percent out of original

percent mean parts out of 100 so x%=x/100

find change first

25 to 50 is a change of 25

now we do
change/original=x%
change/original=x/100
25/25=x/100
1=x/100
x=100

answer is 100% change

25 points to 50 points is a 100% change

100% of 25 = 25

25 + 25 = 50

100% is your answer

hope this helps

What rotation was applied to triangle DEF to create triangle D’E’F’A. 90° clockwise
B. 180°
C. None of the above
D. 90° counterclockwise

Answers

The answer to the rotation of triangle def is B)

Answer:

B. 180°

Step-by-step explanation:

To create triangle D'E'F', you need to rotate triangle DEF 180°, which results a figure with an opposite position, like a mirror. A 180° rotation always gives an opposite position, a mirror effect.
