Expand and simplify (5x^(2)+1)(2x+3)-2x(5x^(2)-3)

Answers

[tex](5x^2+1)(2x+3)-2x(5x^2-3)[/tex] when expanded and simplified gives[tex]15x^2 + 8x + 3[/tex]

What is Expanding?

Expanding is the opening the brackets ( ) or { } for arithmetic operations and simplifying the expression.

How to determine this

[tex](5x^2+1)(2x+3)-2x(5x^2-3)[/tex]

Open of bracket

[tex]10x^3 + 15x^2 + 2x + 3 - (10x^3 - 6x)[/tex]

Collect like terms

[tex]10x^3 - 10x^3 + 15x^2 + 2x +6x + 3[/tex]

=[tex]15x^2 + 8x + 3[/tex]

Responder:

57288.35 kN

Explicación paso a paso:

Paso uno:

datos dados

diámetro del tubo de entrada = 2 cm = 0.02 m

área = πd ^ 2/4

área = 3.142 * 0.02 ^ 2/4

área = 0.0003142m ^ 2

A1 = 3.14 * 10 ^ -4 m ^ 2

diámetro del pistón de salida = 32cm

masa del coche = 1800 kg

peso del coche = 1800 * 10 = 18000N

carga F2 = 18000N

Segundo paso:

Se requiere la presión aplicada P2

Aplicando la ecuación de presión para un fluido incompresible tenemos

P1 = F2 / A1

P1 = 18000 / 0,0003142

P1 = 57288351.36

P1 = 57288.35 kN

36+7x=64 what is the answer ?

Answers

Answer:

x=4

Step-by-step explanation:

First, you need to isolate the variable and constant terms. So, we need to get rid of 36. To do this, we need to take away 36. Now, we have to do this on the other side. 64-36 is 28. Now, the equation is 7x=28.

To isolate the variable, you divide by 7. Again, do this on the other side. 28/7 is 4. Now we have x=4.

Therefore, the correct answer is 4!

Write an equation of the line in slope-intercept form.

Answers

Answer:

y=mx+b where m is the slope and b is where the line crosses the y axis.

THe line crosses the y axis at 0, 2 so 2 = b

the slope is how many units the point goes up/down and to the left/right from the y intercept. From 0, 2 to 3, 3 the point goes up 1 and over to the right 3 times. rise/run is slope so 1/3 is the slope:

y=1/3x+2

Step-by-step explanation:

Answer:

Y= -1/3x + 4

Step-by-step explanation:

Slope equation= y2 - y1/x2 -x1

Subtract 2-3/ 0-3 = -1/3

Choose an ordered pair to use for this problem. I chose 3,3.

Y-intercept equation- y = mx + b

3 = -1/3 * 3 + b

Multiply-1/3 * 3

3 = -1 + b

Add 1 to get rid of -1 and get b alone

3 + 1 = -1 + 1 +b

4= b

Now plug in your numbers to your equation.

Y= -1/3x + 4
