You would use the Pythagorem Theory which is a^2 + b^2 = c^2
the diagonal being c and it doesn't matter how you substitute tho other either a or b. the answer is 15.588 or 15.6 inches

Need help on my math!!!!!!!

(x^2+5x-36)/(x^2-16)
=(x^2+9x-4x-36)/(x^2-4^2)
=x(x+9)-4(x+9)/(x+4)(x-4)
=(x-4)(x+9)/(x+4)(x-4)
=x+9/x+4
Hope this helps.

Y= 5x + 13 <br> and<br> y= x + 45

arsen [322]

Answer:

x=8 and y=53

Step-by-step explanation:

Given function:

y=5x+13
y=x+45

Find x:

the two equation, the x and are breaked apart..
so find a number that they can both equal to together and has the same y.
multiply by 8..
$5$ · $8=40$

combine the terms for x and 13
$40+13=53$

since x is 8 then if we add 8 with 45 it should be 53...
$8+45=53$

y is:

this means that y=53.

Therefore, x=8 and y=53..

<h3>Answer: Approximately 6.4 units</h3>

==================================================

Explanation:

The origin is the point (0,0)

Use the distance formula to find the distance from (0, 0) to (4, -5)

Let

$(x_1,y_1) = (0,0)\\\\(x_2,y_2) = (4,-5)\\\\$

be our two points. Plug those values into the distance formula below and use a calculator to compute

$d = \sqrt{\left(x_1-x_2\right)^2+\left(y_1-y_2\right)^2}\\\\d = \sqrt{\left(0-4\right)^2+\left(0-(-5)\right)^2}\\\\d = \sqrt{\left(0-4\right)^2+\left(0+5\right)^2}\\\\d = \sqrt{\left(-4\right)^2+\left(5\right)^2}\\\\d = \sqrt{16+25}\\\\d = \sqrt{41} \ \text{ exact distance}\\\\d \approx 6.40312 \ \text{ approximate distance}\\\\d \approx 6.4\\\\$

The distance between the two points (0,0) and (4,-5) is approximately 6.4 units.
