** I NEED TO GET THIS RIGHT IM DOING TEST CORRECTION**

valina [46]

Answer: ~27.5

Step-by-step explanation:

I don't know about all the geometry terms, but since a line is 180°, and SE makes 1 right angle (90°), the other side is also 90° (180-90=90).

This means you have a right triangle with sides 15 and 23 and unknown hypotenuse AS.

Pythagorean Theorem: a^2 + b^2 = c^2

(15^2) + (23^2) = AS^2

sqrt( 225 + 529 ) = AS

AS = 27.459

Help plzzz!! Marking most Brainly;)

Answer:

D it

Step-by-step explanation:

We have two equations, A quadratic and a linear equation.

The domain of a linear equation and quadratic equation is all real numbers but since it dealing with time we must make sure the roots or x-intercepts is positive.

Looking at the quadratic equation, we can use the discramnt formula to see if all roots are positve.

$b {}^{2} - 4ac$

${ - 6}^{2} - 4(1)(8.75)$

$36 - 35 = 1$

The discramnt is greater than zero so there is two distinct real roots. So let check if they are positve

If you graph the equation, it intercepts at two positve roots so it is D

The sum of two numbers is 12 and their difference is 18 what are the two numbers

lawyer [7]

Answer:

Step-by-step explanation:

x+y=12

x-y=18

Now eliminate the y by adding the two equations together to get

2x=30

x=15

then solve for y.

15+y=12

15-y=18

y= -3
