6/9 yeah that's it I looked It, up.

Step-by-step explanation:

Answer:

Assuming they are equal to each other, X = -4

Step-by-step explanation:

6x + 25 = x + 5

Subtract 5 from both sides

6x + 20 = x

subtract 6x from the left side

20= 5x

divide by 5

-4 = x

Answer:

Radius = 14 cm, Circumference = 88 cm

Step-by-step explanation:

d = 28 cm

r = 1 / 2 * 28

 = 14 cm

Circumference = 2πr

                         = 2 * 22 / 7 *  14

                         = 2 * 22 * 2

                         = 88 cm

Hope it helps :)

Answer:

the answer is 3

Step-by-step explanation:

how i got this answer is........i did the round robin and i times 1 *5+4 and i got 9  so you will get 3/4 *9/5 and i got 27/9 and you will divided 9*3 and you will get 3 so that is the answer 3

i hope you did good on your test

Answer:

  (c)  h(x) = (3x +4)(2x +1)

Step-by-step explanation:

The answer choices differ in the values they create for the last two terms of the trinomial. The last term (+4) is created by all of the choices except the first one.

The middle term (11x) is only created by the third choice:

  (3x +4)(2x +1) = (3x)(2x) +(3x)(1) +(4)(2x) +(4)(1)

  = 6x^2 +3x +8x +4

  = 6x^2 +11x +4 . . . . matches the given h(x)

Answer:

48

Step-by-step explanation:

You multiply by 2 each time

I believe it is multiplying by 2 each time.

3 x 2 = 6

6 x 2 = 12

12 x 2 = 24

So if this was true to continue we would just multiply by 2....

24 x 2 = 48

48 x 2 = 96

96 x 2 = 192

192 x 2 = 384

384 x 2 = 768

and continue for as long as you need to go....

Answer:

In both cases, we have similar figures.

This means that the shape of the figures is the same, but the size is different:

PQST is similar to STNR and to NRPQ

VUYZ is similar to YZWX and to VUWX

this means that, for example, in problem 18, the ratio between ST and NR must be the same as the ratio between PQ and ST. This happens because the measure increases by the same scale factor.

With this in mind, we can solve the problem:

18)

ST = 7.5

NR = 5.5

Then the quotient ST/NR is:

ST/NR = 7.5/5.5

And, as we said above:

PQ/ST = ST/NR

PQ/7.5 = 7.5/5.5

PQ = (7.5/5.5)*7.5 = 10.23

19) Here we should have:

YZ/VU = WX/YZ

Then:

22.9/35 = WX/22.9

(22.9/35)*22.9 = WX = 14.98

Answer:

3/20

Step-by-step explanation:

Given: Number of cups of pancakes to be made = 20

Number of  bag of chocolate chips available = 3

Therefore, cups of chocolate chips will be in each pancake= 3/20

Answer:

The coordinates of C are (15,16)

Step-by-step explanation:

As we can see, point C lies half the distance of AB

So we can use the midpoint formula to get the coordinates of C

we have this as:

(x,y) = (x1 + x2)/2 , (y1 + y2)/2

(x1,y1) = (3,2)

(x2,y2) = (27,30)

Thus, we have

(x,y) = (3 + 27)/2, (30 + 2)/2

(x,y) = 30/2 , 32/2

(x,y) = (15,16)

Answer: (1. 10 9/10.) (2. 6 5/6) (3. 2 2/8) (4. 28 1/8) 5. 1.5 or 1 1/2

Step-by-step explanation:

Answer: 45 liters

Step-by-step explanation:

If Roger jars 15 liters of jam in 2 days, we can divide to see how much liters of jam Roger can jar in 1 day. We can divide 15 by 2 to find how much jam can be jarred in one day.

15 / 2 = 7.5.

Roger can jar 7.5 liters of jam every day.

Now we can multiply 7.5 by 6 to find how much jam Roger can jar at the end of 6 days.

7.5 x 6 = 45.

Therefore, Roger can jar 45 liters of jam in 6 days.

Answer:

80p2 - 180r2

20(4p²-9r²)

20(2p+3r)(2p-3r)

Answer:

20(2p - 3r)(2p + 3r)

Step-by-step explanation:

Given

80p² - 180r² ← factor out 20 from each term

= 20(4p² - 9r²) ← difference of squares which factors in general as

a² - b² = (a - b)(a + b)

4p² - 9r²

= (2p)² - (3r)² ← with a = 2p and b = 3r

= (2p - 3r)(2p + 3r)

Thus

80p² - 180r² = 20(2p - 3r)(2p + 3r) ← in factored form

plz mark as brainliest

Step-by-step explanation:

Answer:

Ver respuesta abajo

Step-by-step explanation:

Una ecuación cuadrática es una ecuación que tiene la siguiente forma:

ax² + bx + c = 0

Donde:

a, b y c: coeficientes numéricos que acompañan a la incógnita.

Ahora bien, una función cuadrática es basicamente la misma ecuación cuadrática pero representada graficamente en un plano cartesiano.

Para que una ecuación o función sea cuadrática es absolutamente necesario y obligatorio que su expresión en forma de ecuación tenga el elemento "ax²", pues el "cuadrado" que es el exponente 2 que eleva la incógnita es lo que le da la característica de ecuación o función cuadrática.

Si el coeficiente que acompaña al x², es decir, el valor de a es cero, automaticamente pierde la condición de ser una función o ecuación cuadrática pues dicho término se hace cero su valor. En otras palabras, si x es un número cualquiera y está representado como incógnita, ¿qué sucede cuando multiplicas cualquier número por cero?, en este caso, el resultado es igual a cero:

Ejemplo:

0x² = 0 * x² = 0.

Por tanto, si el término cuadrático se hace cero, ya pierde la condición de cuadraticidad, y su gráfico no sería de forma parabólica, solo quedaría los términos bx + c, pero eso ya pertenece a una ecuación lineal o función afín.

Espero esto te sirva.

Answer:

The answer is 9.

Step-by-step explanation:

If x equals 3 and you have 3x its basically just 3 times 3 so you get 9 as the result.

Answer:

143

Step-by-step explanation:

Substitute n=3 into the problem

6([tex]3^{3}[/tex])-2([tex]3^{2}[/tex]) +3-4

Then figure out squared and power by 3

6(27)-2(9)+3-4

Next multiply

162-18+3-4

Finally, add and subtract

144+3=147

147-4=143

Answer:

21 = x( x+4)

Step-by-step explanation:

21 = x(x+4)

This equation is used because two sides are being multiplied by each other and the second one is four feet longer than the other one.
