Let us assume the two numbers to be "x" and "y".
Then
xy = - 24
x = - (24/y)
And
x + y = 2
Putting the value of x from the first equation in the second equation, we get
x + y = 2
- (24/y) + y = 2
- 24 + y^2 = 2y
y^2 - 2y - 24 = 0
y^2 - 6y + 4y - 24 = 0
y(y - 6) + 4(y - 6) = 0
(y - 6) (y + 4) = 0
When
y - 6 = 0
y = 6
Then
x + y = 2
x + 6 = 2
x = 2 - 6
   = -4
And when
y + 4 = 0
y = -4
Then
x + y = 2
x - 4 = 2
x = 2 + 4
   = 6
So the two unknown numbers are -4 and 6.

I don’t get how you do this please help

This is just a reflection. Not sure what your question is so I’ll just explain reflections. Reflections are flipping a shape across that certain line. Here, it is the X axis. What I usually do is see how far away each point is away from the (line of reflection) x axis. For example, G is 5 points away from the x axis, so the reflection of G is also 5 points away from the x axis. This works with any point of the shape. Hope this helped!

One leg in a right triangle is 11 ​m, and the hypotenuse measures 11√2 m. Find the length of the other leg.
ipn [44]

Answer:

\boxed{11m}

Step-by-step explanation:

Method #1: 45-45-90 Triangle

You can use the rules for a 45-45-90 triangle. These are:

→ Each 45-45-90 triangle is a right triangle with two additional 45° angles.

→ The triangle will have 2 legs, <em>x</em>, and one hypotenuse, <em>x</em>√2.

Therefore, because the problem gives values for one leg and the hypotenuse, the value for the one leg is equal to the value for the unsolved leg.

Method #2: Pythagorean Theorem

You can use the Pythagorean Theorem to solve for a missing side in a triangle. Please note, however, that the Pythagorean Theorem only works on <u>right</u> triangles.

The Pythagorean Theorem is defined as a^{2} + b^{2} = c^{2}, where <em>a</em> and <em>b</em> are both legs of the triangle and <em>c</em> is the hypotenuse.

Therefore, substitute the known value for <em>a</em>, 11, and the known value for <em>c</em>, 11√2. Then, evaluate each value to its power (except for <em>b </em>- it is unsolved) and simplify the equation with basic algebraic methods. Once your equation is down to b^{2}= ?, you should take the square root of both sides of the equation to get the value for <em>b</em>.

11^{2} +b^{2} =(11\sqrt{2} )^{2}\\121 + b^{2} = 242\\b^{2}=121\\b=11
