Which correctly describes how the graph of the inequality 5x + 2y > 13 is shaded?

Leya [2.2K]

Answer:

We can't graph on this app but this is what I can give you.

Step-by-step explanation:

The 5+2 part automatically makes 7, obviously, meaning that x and y each would have to at least represent 2 for this equation to be true.

I'm stuck on this question, please help. Thank you!!!

Let's multiply each of the four squares, one by one.

In blue, we see the dimensions are x by x. x times x = x^2

In pink, we see the dimensions are 9 by x. x times 9 = 9x

In green, the dimensions are x by 3. 3 times x = 3x

And finally, yellow's dimensions are 3 by 9. 3 times 9 = 27

We can now just add all these areas to find the total area:

x^2 + 12x + 27

Answer:

Mike is not right

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its surface areas is equal to the scale factor squared

Let

z----> the scale factor

x----> surface area of the enlarged rectangular prism

y-----> surface area of the original rectangular prism

$z^{2}=\frac{x}{y}$

In this problem we have

$z=2$

substitute

$2^{2}=\frac{x}{y}$

$4=\frac{x}{y}$

$x=4y$

The surface area of the enlarged rectangular prism is 4 times the surface area of the original rectangular prism

therefore

Mike is not right

<em>Verify with an example</em>

we have a rectangular prism

$L=5\ m$

$W=2\ m$

$H=3\ m$

The surface area of the prism is equal to

$SA=2(LW)+(2L+2W)H$

substitute the values

$SA=2*(5*2)+(2*5+2*2)*3=62\ m^{2}$

If he doubles each dimension of any rectangular prism

then

the new dimensions will be

$L=5*2=10\ m$

$W=2*2=4\ m$

$H=3*2=6\ m$

The new surface area will be

$SA=2*(10*4)+(2*10+2*4)*6=248\ m^{2}$

$248/62=4$

therefore

The surface area of the enlarged rectangular prism is 4 times the surface area of the original rectangular prism
