Answers
Answer:
8x^2+32x+24
Step-by-step explanation:
Use the FOIL method:
(8x+8)(x+3) = 8x^2 +24x +8x +24
Simplify: 8x^2 + 32x +24
Answer:
8x^2 + 32x + 24
Step-by-step explanation:
What's the FOIL method?
For this question, we're going to use something called the FOIL method. First, let's take random polynomials and multiply them together, such as (3x + 2)(5x + 6). FOIL stands for First, Outside, Inside Last. The first numbers would be: (3x + 2)(5x + 6). The outside numbers would be (3x + 2)(5x + 6). The Inside numbers would be (3x + 2)(5x + 6). The last numbers would be (3x + 2)(5x + 6).Solving Product of Polynomial

List the angles of the given triangle from smallest to largest. Explain your reasoning. Solve for x.
Answers
Answer:
Smallest to Largest: Angle ACD, Angle ADC, Angle CAD, Angle ACB
Step-by-step explanation:
To find the angles, let's first solve for x.
Let's call the missing side angle ACD= y
We know that there are 180 degrees in a triangle. So we can write the equation,
6x+4+(4x-2)+y= 180
and, We know that angle ACB is a linear pair with angle ACD, so both angles would add up to 180 degrees. We can write the equation,
9x+16+y=180
Let's now solve for x with both of these equations using elimination.
Simplify the equations,
6x+4+(4x-2)+y= 180 -> 10x+y=178
9x+16+y=180 -> 9x+y=164
-1(10x+y=178) -> -10x-y=-178
-10x-y=-178
9x+y=164
-x= -14
x= 14
Now that we have solved for x, we can find the missing angles.
Angle ACB= 9x+16 -> 9(14)+16= 142 degrees
Angle CAD= 6x+4 -> 6(14)+4= 88 degrees
Angle ADC= 4x-2 -> 4(14)-2= 54 degrees
Angle ACD= 180-(Angle CAD+ Angle ADC) -> 180-(88+54)= 38 degrees

There are 2 ways to look at this. I will explain both.
First we have the 3-4-5 triangle method, stating that any triangle with sides 3 and 4 will have the last side as 5.
Now, for the more complex way of doing this, we can use the Pythagorean theorem to solve this problem.
Pythagorean theorem: [tex]a^2+b^2=c^2[/tex]
We can use 4 for a and 3 for b
You will now have
[tex]4^2+3^2=c^2\\\\16+9=c^2\\25=c^2[/tex]
Then take √25, or 5.
Use the unit rate to fill in the blank.

If each novel cost the same amount, how much did I novel cost?
Answers
Answer:
I am sure it's $8
Step by step explanation:
Total money spent= $82
Cost of dictionary= $26
Cost of 7 novels = $82 - $26
= $56
Cost of 1 novel = $56/7
= $8
Therefore, each novel bought by Esme cost $8

the sum of the page numbers on two integers facing pages in a book is 941.how many pages does the book have??.
Answers
Step-by-step explanation:
x + x+1 = 941
2x + 1 = 941
2x = 940
x = 470
but the question is wrong or cannot be answered bad in the given information.
the question sounds be : what are the page numbers ?
the answer : 470 and 471.
but "how many pages does the book have" cannot be answered.
the book could have 471 pages. but also 2000. or 4000. or, or, or...
it does not change anything about the relationship of the pages 470 and 471. and there is therefore no way to know the total number of pages of the book just by knowing that there are pages 470 and 471.
A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 6 inches.
Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 6) would represent a height of 6 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points)
Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points)
Part C: If the rate at which the candle burnt was 0.3 inches per hour instead of 0.5 inches per hour, will the relation continue to be a function? Explain your answer using input and output values. (3 points)

Answer:
x = (64 + 5) ÷ 3
Step-by-step explanation:
3x - 5 = 64
Add 5 to both sides: 3x = 64 + 5 = 69
Divide both sides by 3: x = 69 ÷ 3 = 23
So the answer is x = (64 + 5) ÷ 3
Note: If we didn't add the parentheses then using the order of operation x = 64 + 5 ÷ 3 would be x = 64 + [tex]\frac{5}{3}[/tex] = 65 [tex]\frac{2}{3}[/tex]

One side of a triangle is half the longest side. The third side is 11 feet less than the longest side. The perimeter is
54. Find all three sides.
Answers
Answer:
13, 15, 26
Step-by-step explanation
Let one side by "x". The longest side will be 2x, and the 3rd side will be 2x-11. Since they all have to add up to 54, we can form this equation: x+2x+2x-11=54, x=13.
You plug the values back in: (13), 2(13)=26, and 2(13)-11=15.
Susan wants to have 30% of her gumballs be green If there are

Answers
Answer:
15 gumballs
Step-by-step explanation:
There would have to be...
30%*50 green gumballs
We can start by converting 30% to a fraction. Any percentage is just that number over one hundred so...
30/100*50
We can simplify 30/100 by dividing the numerator and the denominator by 10...
3/10*50
Cancel out 10 and 50 (50/10=5)
3*5
15 gumballs would have to be green
Answer:
15 gumballs would have to be green.
To solve this question, you would need to figure out what is 30% of 50.

4 -(-4) = 8 . . . units
That is, y' = y +8. This matches choice C.
The translation of Y(4, -4) to Y'(-2, 4) is described by ...
