Domains : Those values of x for which function is defined.
Range: Values of y for corresponding values of x belonging to domain.

Here domain is all real values and range is all real values. Hence B and D are correct.

Calculate the surface area and show work :) please help me no links!!

eimsori [14]

Answer:

294 in.²

Step-by-step explanation:

I believe this figure is a rectangular prism.

------------------------------------------------------------------------------------

Explain:

To find the surface area of a rectangular prism, use this formula:

$SA=2lw+2lh+2wh$

$SA=2(lw+lh+wh)$

$l-length$

$w-width$

$h-height$

A phrase I use to help remember this formula is:

LISA WILSON LOST HER WITCH HAT TWICE (2)

------------------------------------------------------------------------------------

Solve:

The length of this rectangular prism is 9 in.

This width is 10 in.

The height is 3 in.

Now, I will plug the numbers into the first formula.

$SA=(2*9*10)+(2*9*3)+(2*10*3)=294 in.^2$

------------------------------------------------------------------------------------

Conclude:

I, therefore, believe the area of this rectangular prism is 294 in.²

Solve the following quadratic equation: x/x+3 = 5/2x+6

Leni [432]

Answer:

$x=5/2, x=-3\\$

Step-by-step explanation:

$x(2x+6)=5(x+3)\\2x^2+6x=5x+15\\2x^2+6x-5x-15=0\\2x^2+x-15=0\\2x^2+6x-5x-15=0\\2x(x+3)-5(x+3)=0\\(2x-5)(x+3)=0\\2x-5=0, x+3=0\\x=5/2, x=-3\\$

Write any two quadratic equations.

Thepotemich [5.8K]

To find:

Any two quadratic equations.

Solution:

The general form of a quadratic equation is:

$ax^2+bx+c=0$

Where, a,b and c are real number and a is non zero.

We know that a,b,c can take any values but a cannot be 0.

For a=1, b=1,c=1, we get

$1x^2+1x+1=0$

$x^2+x+1=0$

One quadratic equation is $x^2+x+1=0$ .

For a=3,b=-1,c=5, we get

$3x^2+(-1)x+5=0$

$3x^2-x+5=0$

Therefore, the two quadratic equations are $x^2+x+1=0$ and $3x^2-x+5=0$ .
