how do you solve these kinds of equations? (3x+5) (3x+5)

Answers

Answer 1

Answer:

-5/3

Step-by-step explanation:

(3x+5)(3x+5) is the factored form of the quadratic: 9x^2+30x+25

In equation form, it will be 9x^2+30x+25 = 0 so we have:

(3x+5)(3x+5) = 0

To solve these types of equations, we find the roots. Since the product of these numbers is 0, (3x+5) has to be equal to 0.

3x + 5 = 0

Subtract 5

3x = -5

Divide by 3

x = -5/3

Answer:

1st scenario: 163.3°

2nd scenario: 125.2°

3rd scenario: 142.3°

Step-by-step explanation:

1st scenario: angles 1 and 2 form a linear pair and add up to 180

2nd scenario: angles 1 and 4 are same-side interior and add up to 180

3rd scenario: angles 1 and 8 are corresponding and equal; if angle 7 is 37.7 then angle 8 is 142.3 (they form a linear pair). Since angles 1 and 8 are equal then angle 1 is also 142.3

Answers

Answer:

36 ft

Step-by-step explanation:

The ratio of the lengths of the sides is the same as the ratio of the perimeters.

Just like one side (15 ft) of triangle ABC is 3 times as long as the corresponding side (5 ft) of triangle DEF, the perimeter of triangle ABC is also 3 times the perimeter of triangle DEF.

15/5 = x/12

3 = x/12

x = 36

Answer: 36 ft

Find angles a, b and c?
Please help.

Answers

Answer:

B=112 degrees A=68 degrees and C=68 degrees

Step-by-step explanation:

the opposite angle of the 112-degree angle is the angle on the top left of the page, this means both of the angles are the same. You can then tell that that angle is the same as the one across from it because it shows on the page.  You can then figure out the opposite angle which is B so that means angle B is equal to 112 degrees. To figure out angle A you can just do 180 minus the angle B which is 112 degrees. You now know angle A which is 68 degrees, now to find the angle C you just have to notise that angle C is the opposite angle of angle A. This means that algle C is also 68 degrees.

Answer:

a=112

b=68

c=112

2b-(3-b) + 4 = 11
I need to know how to show the work to get this answer

Answers

Answer:

10/3

Step-by-step explanation:

Simplifying 2b - (3-b) gives us:

2b - (3 - b) =

2b - 3 + b =

3b - 3

This makes our new equation:

3b - 3 + 4 = 11

Combine like terms

3b + 1 = 11

Subtract 1 from both sides

3b = 10

Divide both sides by 3

b = 10/3

Blank 1 = 3Blank 2 = 3

In other words, x = 3  and y = 3

===========================================================

Explanation:

Let's solve the first equation for x. I'm picking on this equation variable because the coefficient is 1.

Solving for x leads to

x-2y = -3

x = -3+2y

I added 2y to both sides

Now we'll plug this into the other equation. This means we replace every copy of x with -3+2y since they are the same thing.

3x + 5y = 24

3( x ) + 5y = 24

3( -3+2y ) + 5y = 24 .... replace x with -3+2y

3(-3) + 3(2y) + 5y = 24 .... distribute

-9 + 6y + 5y = 24

11y-9 = 24

11y-9+9 = 24+9 ...... adding 9 to both sides

11y = 33

11y/11 = 33/11 .... dividing both sides by 11

y = 3

We'll use this y value to find x. We can pick on any equation with x & y in it, but I find it's easiest to use the equation where x is isolated

x = -3+2y

x = -3+2(3) .... replace y with 3

x = -3+6

x = 3

So both x and y are equal to 3

-------------------------------

Let's check the answer

Plug (x,y) = (3,3) into the first equation. We should get the same number on both sides after simplifying fully

x-2y = -3

3 - 2(3) = -3

3 - 6 = -3

-3 = -3

So far, so good. Let's try the other equation

3x + 5y = 24

3(3) + 5(3) = 24

9 + 15 = 24

24 = 24

The other equation is true as well. This fully confirms that (x,y) = (3,3) is the solution to this system of equations. If you graphed each original equation, you should find they cross at the location (3,3).

Side note: it won't always be the case that x and y are the same value.

Oliver, Lily, and Ella are hoping to save money. Oliver thinks saving money in a shoe box in his closet every month is a good idea. He decides to start with $150, and then save $75 each month. Lily was given $4000 from her Great Uncle Merv, and decides to put the money into an account that has a 7% interest rate that is compounded annually. Ella has earned $4500 working at the gas station and decides to put her money in the bank in an account that has a 7.5% interest rate that is compounded continuously. Part 1: Describe the type of equation that models Oliver’s situation. Create that equation of Oliver’s situation. Using the equation you created, how much
money will be in Oliver’s account after 2 years? 10 years?

1. What is being asked in the problem and what does that mean?
2.What do you know and what does it mean? What plan are you going to try?
3. Write out your thinking and work.
4. Write out your response to the question, explaining your answer and what it means.

Answers

Answer:

Step-by-step explanation:

Part 1:

1. What is being asked in the problem and what does that mean?

Oliver is meaning to save more money than Lilliana

2.What do you know and what does it mean? What plan are you going to try?

It means that Oliver is trying to be reponsible and save money for a nice house. Use an equalizer and solve it.

3. Write out your thinking and work.

Since Olivier saves 150 per month, we multiply that with the number of years and then subtract the $75 he already saved up (since we only need to calculate the amount that he saved over the months.

2 yr of months: 150x30 -75 = 4480

10 yr of months: 150x180 - 75 = 21,993

4. Write out your response to the question, explaining your answer and what it means.

2 months of years: $4480

10 months of years: $21993

Part 2:

1. What is being asked in the problem and what does that mean?

Liliana needs to save money and we are asked to help her.

2.What do you know and what does it mean? What plan are you going to try?

It means that we have to use an equalizer to give to her so she can save the money over the years.

3. Write out your thinking and work.

Use formulaic methods. Since she has interest on her money, we have to include it:

i = log(x-4*7)^k

i is the interested amount, x is the variable we use, and k is the number of times. 7 is the interest

i = log(4000-4*7)^2 for 4000 at 7% interest over 2 years

i = log(4000-4*7)^10 for 4000 at 7% interest over 10 years

4. Write out your response to the question, explaining your answer and what it means.

Amount after 2 years: $30,000

Amount after 10 years: $15,671

Part 3:

1. What is being asked in the problem and what does that mean?

How we can help Ella save for her college.

2.What do you know and what does it mean? What plan are you going to try?

We can try using formulaic methods like we did for Dan in the previous assignment.

3. Write out your thinking and work.

l = (a/b)^q where l is the amount saved, a is the initial amount of dollars, b, is the time, and q is the interest

2 years: (4500/2)^4.5 = 2,500

10 years: (4500/10)^4.5 = 40,650

4. Write out your response to the question, explaining your answer and what it means.

After 2 years: $2500

After 10 years: $40,650

Ella would be able to afford college (if she does community college, but not a private university).
