Form a quadratic equation and find the length of AB ​

Hiii! Can Someone Please Help Me With My Maths QuestionForm A Quadratic Equation And Find The Length

Answers

Answer 1

Step-by-step explanation:

a^2 + b^2 = c^2

(x+2)^2 + 4x^2 = (3x+4)^2

(x+2)(x+2)+ 4x^2= (3x+4)(3x+4)

x^2 + 2x + 2x + 4 + 4x^2 = 9x^2 + 12x + 12 x + 16

5x^2 + 4x + 4 = 9x^2 + 24x + 16

-4x^2 - 20x - 12 = 0

now we can use the quadratic formula

(-b±√(b²-4ac))/(2a)

I can't type all this so

.....

x = -0.697224362 or -4.302775638

AB can't be negative so it's the first one

so it's equals to 1.302775638

I assume the following equation is the question you asked.

[tex] \rightarrow \sf \: 2(x - 1)(x + 2)[/tex]

If yes, these are the following are the steps to reach your answer :-

[tex]\sf \: 2(x - 1)(x + 2)[/tex]

Use the distributive property to multiply 2 by x - 1.

[tex] \sf \: \left(2x-2\right)\left(x+2\right) [/tex]

Apply the distributive property by multiplying each term of 2x - 2 by each term of x + 2.

[tex] \sf \: 2x^{2}+4x-2x-4 [/tex]

Combine 4x and - 2x to get 2x.

[tex] \boxed{ \bf \: 2x^{2}+2x-4 }[/tex]

=> The answer will be 2x² + 2x - 4.

Please anyone help please I’m stuck with this question please help please ASAP show work Too

Answers

This is the flip side of the previous one I answered. The range is the set of all y-values or outputs. Since you can only spend increments of $1.25, you cannot have all the numbers from 12 to 0 in your range.

The range is 12 dollars minus all possible increments of 1.25, until you can’t buy any more candy.

12
12-1.25 = 10.75
10.75-1.25 = 9.50
And so on.

The answer is D.

The data set and some summary statistics are listed.

11.5, 12.3, 13.5, 15.6, 16.7, 17.2, 18.4, 19, 19.5, 21.5

Mean: 16.52

Median: 16.95

Standard Deviation: 3.11

IQR:5.5

How does adding 5 to each of the values in the data set impact the measures of variability?

Answers

Answer:

see below:

Step-by-step explanation:

the median will become a larger, different number. The mean will also become a larger number, since it will still be dividing by the same amount of numbers in the equation, only the quantity will become larger. Same with standard deviation. The IQR will change, because the amount of the two numbers you'll be subtracting will end up greater than before.

Help me with number 23 plsssssss

Answers

The Answer is:

p=15

5x3=15

So that must mean 15/5=3

Hi! I'm happy to help!

To make this equation easier, we can use the inverse operation, multiplication (instead of division).

p÷5=3

3×5=p

Doing this will give you the same answer, it just makes it easier. 3 times 5 is 15, so p=15

We can double check our answer by putting in 15 for p.

p÷5=3

15÷5=3, this is true, so our answer is correct.

I hope this was helpful, keep learning! :D

What is a magnetic field?

The magnetic field is defined as the field the magnetic materials generate or when an electric charge moves in a field region that generates the magnetic field.

It is given that:

A tool is a compass tool which is an indicating the north direction.

As we know,

The magnetic field is defined as the field the magnetic materials generate.

A metal object with two legs, one for a pencil and one with a tip.

Thus, the best describes compass tool is a metal instrument with two legs-one with a point and one for a pencil option (c) a metal instrument with two legs-one with a point and one for a pencil.

Let call X the origninal price.

if it rose of 20 % , it's mean that it' be multiplicate by 1.20

Hi

Golden rule to know by heart : you can only add or substract element of the same kind.

so X^2 with X^2 , X with X , numbers with numbers...

exemple : 2X^2 +3X^2 = 5X^2

but 5X^2 -3X remains that way as 5X^2 is a " X^2" and " 3X" is a " X" so I can't substract two elements of different kind.

Now you have to translate what is ask of you into a calculus.

so : you have

A ) ( 2x^2+4x +5) - ( x^2+3x)

Math is a sport of the mind. You will only progress and become stronger if you train.

So I let you have a shot. beware of signs rules. If you still have trouble, ask in comment section..
