Answer:

=10x^2+8x+3

Step-by-step explanation:

Lets simplify step by step.

=5x^2+3x+4+5x^2+5x+-1

Combine like Terms.

=5x^2+3x+4=5x^2+5x=-1

=(5x^2+5x^2)+(3x+5x)+(4+-1)

=10x^2+8x+3

Is (0,0) a solution to 6x - 7y > 20 please include the steps!

leonid [27]

Answer:

No.

Step-by-step explanation:

To determine if (0,0) is a solution to the inequality, substitute 0 for x and 0 for y and check to see. Thus:

$6x-7y>20$

Substitute 0 for x and 0 for y:

$6(0)-7(0)\stackrel{?}{>}20$

Multiply:

$0-0\stackrel{?}{>}20$

Subtract:

$0\not>20$

So, (0,0) is not a solution.

And we're done!

I believe your answer is:

18in³

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

Assuming that the figure is a rectangular prism:

⸻⸻⸻⸻

$\boxed{\text{Volume of a rectangular prism is:}}\\\\V = l * w * h\\-----------\\V = 2 * 2.25 * 4\\\\\boxed{V = 18}$

⸻⸻⸻⸻
