Mathematics
1 answer:

Answer:

The answer would be 36\sqrt{2\\\\} or 50.91

Step-by-step explanation:

The way you would do this is that the diagonal of the square creates two right triangles. Both of the triangles created are 45, 45, 90 triangles.

In all cases of the 45,45,90 triangles the sides are 1/2 \sqrt{2\\\\}  of the hypotenuse aka the diagonal.  

So to solve, you would just multiply the diagonal by 1/2 \sqrt{2\\\\}  and you have your answer.

Y= (x-9) (x+3)
juin [17]

Answer:

y = x² − 6x − 27

Step-by-step explanation:

To distribute, you can use something called FOIL.  It stands for First, Outer, Inner, Last.

First, multiply the First term in each factor.

x · x = x²

Now multiply the Outer terms in each factor.

x · 3 = 3x

Next multiply the Inner terms in each factor.

-9 · x = -9x

Finally, multiply the Last terms in each factor.

-9 · 3 = -27

Add them all up:

x² + 3x − 9x − 27

x² − 6x − 27
