Explain how to square a binomial.

Answers

Answer 1

Answer:

Put parentheses around the binomial and then expand it, and then use foil

Step-by-step explanation:

Let's say I have the binomial x+y.

(x+y)^2

(x+y)(x+y)

x^2+xy+xy+y^2

x^2+y^2+2xy

Answer 2
Answer: Here's what I would do using the FOIL method:
1. Multiply the first terms
2. Multiply all the outer terms
3. Multiply all the inner terms
4. Multiply the last terms
5. Combine like terms
Example problem: (x+3)^2 = (x+3) (x+3)
1. (x) (x) = x^2
2.(x) (3) = 3x
3. (3) (x) = 3x
4. (3) (3) = 9
5. Combine like terms solution:
x^2 + 6x + 9

Solve by Substitution :

// Solve equation [1] for the variable  y

 [1]    y = 2x

// Plug this in for variable  y  in equation [2]

  [2]    -2•(2x) - 8x = 24

  [2]     - 12x = 24

// Solve equation [2] for the variable  x

  [2]    12x = - 24

// By now we know this much :

   x = -2

// Use the  x  value to solve for  y

she make?

Answers

Answer:

Amy puede hacer 4 conjuntos.

Step-by-step explanation:

La solución sería

Se sabe que un conjunto de vestir se compone de camisa o blusa, pantalones, zapatos y cinturones, aunque este ultimo es opcional.

Lo que haremos es esto, empezamos a coger una pieza de cada prenda para armar un conjunto.

Primer conjunto:

1 blusa, 1 pantalón, 1 cinturón, y 1 par de zapatos.

Y esto quedaría así: 3 pantalones, 6 blusas, 1 cinturón y 4 pares de zapatos.

Segundo conjunto:

1 blusa, 1 pantalón, 1 cinturón y 1 par de zapatos.

Esto quedaría así: 2 pantalones, 5 blusas, 0 cinturones, 3 pares de zapatos. Sabemos que el cinturón es opcional, así que podemos continuar.

Tercer conjunto:

1 blusa, 1 pantalón y un par de zapatos.

Esto quedaría así: 1 pantalón, 4 blusas, 0 cinturones y 3 pares de zapatos.

Cuarto conjunto:

1 blusa, 1 pantalón y un par de zapatos.

Esto quedaría así: 0 pantalones, 3 blusas, 0 cinturones y 2 pares de zapatos. Como en un conjunto el pantalón es prioridad, al no tener más pantalones los conjuntos quedarían hasta aquí.

Answer:

  (x, y) = (9, 17)

Step-by-step explanation:

Any two pairs of equations can be used to form a system of equations that will give appropriate values of x and y. Let's set the upper and lower left expressions equal to the middle one.

  2x +3y -20 = 4x +5y -72 . . . . upper left = middle

  52 = 2x +2y . . . . . . . . add 72-2x-3y

  x + y = 26 . . . . . . . . . . divide by 2

and ...

  5x -2y +38 = 4x +5y -72 . . . . lower left = middle

  110 = -x +7y . . . . . . . . . . . . . add 72-5x+2y

Now we have two equations in two unknowns that will give us the common values of x and y. Adding these equations eliminates x and gives the value of y:

  (x +y) +(-x +7y) = (26) +(110)

  8y = 136 . . . . . . . . simplify

  y = 17 . . . . . . . . . divide by 8

  x = 26 -y = 26 -17 = 9

The values of x and y that make all of these expressions equal are ...

  (x, y) = (9, 17)

The value they are equal to is ...

  2x +3y -20 = 2(9) +3(17) -20 = 18 +51 -20 = 49

__

Check

  upper right = 9 -4(17) +108 = 9 -68 +108 = 49

  lower right = 3(9) -17 +39 = 27 -17 +39 = 49

Step-by-step explanation:

Let the third side is x.

According to Triangle-angle-bisector theorem, we have the possible ratios:

x/7.5 = 2/5

or

x / 7.5 = 5/2

Solve for x in each case:

1)

x = 7.5*2/5 = 3 cm

im having trouble solving this. y=5(x-3)​

Answers

Hi there!!

  If you need  X to be solved then the answer is X=Y over 5+3 and if your looking for the answer for Y then the answer is Y=5x−15

                                                 

When you are solving for X you will need to use the distributive property so you can multiply 5 by X-3.

Y=5x-15. Once you've done that then you need to swap sides so all of the variables are on the same side as each other  (they need to be on the left side) 5x-15=Y.

Then you need to add 15 to both of the sides to make it look like this     ->5x=Y+15

When that's done you then need to divide both sides by 5 so it then looks like this when done.

5x over 5= Y+15 over 5

When you divide this by 5, it then undoes the multiplication by 5.

X= Y+15 over 5

Finally, you need to divide Y+15 by 5

X=Y over 5 plus 3

                                 

When solving for Y, all you will need to do is use the distributive property to multiply 5 by X-3.
