Hiii! can someone please help me with my maths question

Form a quadratic equation and find the length of AB ​

Answer:

- 3x² + x + 5

Step-by-step explanation:

- 2x² + 4x + 5 - (x² + 3x) ← distribute by - 1

= - 2x² + 4x + 5 - x² - 3x ← collect like terms

= - 3x² + x + 5

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..

Answer:

2(x+6) + 2(x) =40

2x +12+2x=40

4x+12=40

4x=28

x=7

Now to find area it is LxW

7x13=91

So the area of the rectangle is 91 meters squared

Step-by-step explanation:

Answer:

Area=120[tex]cm^{2}[/tex]

Perimeter =44[tex]cm^{2}[/tex]

Step-by-step explanation:

area=length(l)*width(w)    

      =12*10                        

     =120[tex]cm^{2}[/tex]

perimeter=2(length+width)

                =2(12+10)

                =2*22

               =44[tex]cm^{2}[/tex]

Answer:

5,166,000

Step-by-step explanation:

grown population after 1 year=2.5/100×5040000

which is 126,000

total population after 1year=5040000+126000

which is 5166000

Step-by-step explanation:

just for reference I can't guarantee

The best described 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.

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.

Answer:

2

Step-by-step explanation:

steps are in picture.Ignore hand writing

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

Answer:

-8.5

Step-by-step explanation:

If I'm not mistaken this is true because the opposite of a whole number (That isn't 0) is always the negative

Answer:

please mark me brainliest

Step-by-step explanation:

7=3x-5-5x

7=3x-5x-5

7=-2x-5

7+5=-2x

12=-2x

x=12/-2

×=-6

Answer:

-6 = x

Step-by-step explanation:

7 = x + 2x - 5 - 5x

~Combine like terms

7 = -2x - 5

~Add 5 to both sides

12 = -2x

~Divide -2 to both sides

-6 = x

Best of Luck!

Hi

Let call X the origninal price.

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

so :

X*1,2 = 25.8

1.2X=25.8

As math is all about method and training, I let you have a try and resolve the equation. If you do not know how, ask in comments section.

Answer:

C(1,4) , A(-2,-3), R (3,2)

Step-by-step explanation:

the formula thing for rotating 180° about the origin is (x,y) -> (-x,-y)

this doesn't mean make the number negative, but make it the opposite if that makes sense

e.g. F(2,-4) -> F(-2,4)

Answer:

I think no 4 shows the best position for 3

Answer:

B. 1/81

Step-by-step explanation:

f(-4) = 3(-4)

f(-4) = -12

Hope that helps.

-12,1/243,-64 or 1/81

1/81 would be the correct answer to the equation hope this helps

evaluate the function rule for the given value.

f(x)=3^x for x=-4

-----

f(-4) = 3^(-4)

---

f(-4) = (1/3)^4

---

f(-4) = 1/81

Answer:

Step-by-step explanation:

2,3,5,6, 8,11,13          Are correct.

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.

(this is just what mine said, i hope this helped at least a little bit!! Sorry if our websites are different, have a nice day!) :)

[tex]\boxed{\underline{\bf \: ANSWER}}[/tex]

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.

Answer:

So the answer is H

Step-by-step explanation:

They could be situated as

x y z

in which case xy 5 and yz = 3

The total would be 8.

if they are situated like this

x z y

then xy = 5 and yz = 3 but its going the opposite way.

5 - 3 = 2
