Answer:

24.

Step-by-step explanation:

Substitute each instance of x with a 3.

That leaves us with 3^2 + 3x - 5 + 3^2 - 3x + 11.

Combine like terms.

2(3^2) + 6.

Simplify.

2(9) + 6

18 + 6

Answer:

24

Step-by-step explanation:

To solve this equation, you can first simplify the equation by combining like terms. For example, we have two positive x²'s meaning we can simplify this to 2x². After simplifying you should get:

2x² + 6

(We no longer have any values with just x since the positive 3 and negative 3 cancel each other out)

Now, you need to input 3 wherever there is an x. I would suggest putting parenthesis wherever you input this value to avoid confusion.

You should get this:

2(3)² + 6 =

From there, you can start solving the equation to get your answer. You should get something similar to this:

2(9) + 6 =

18 + 6 = 24

~Hope this helps!~

study the diagram of circle K where JL and LM are tangent to circle K at points J and M respectively. Also JL=3x+10 and ML =7x-6
Verdich [7]

Answer:

22

Step-by-step explanation:

The answer is 22. You solve the equation 3x+10=7x-6 like so

3x+10=7x-6

-3     = -3

    10= 4x-6

   +6         +6

     16=4x

      x=4

You then plug in the value of x to the equation for LM.

7x-6 becomes 7*4-6 which is 22.

△MNP ≅ △TUS. Use the picture below to solve for the following: x, y, and m∠N.
Katyanochek1 [597]

Answer:

x = 32

y = 51

m∠N = 14°

Step-by-step explanation:

Given:

ΔMNP ≅ ΔTUS

By the property of similarity,

MN ≅ TU, NP ≅ US and MP ≅ TS

m∠M = m∠T = 142°,

m∠N = m∠U = (2x - 50)°

m∠P = m∠S = 24°

Since, m∠N = [180°- (m∠M + m∠P)]

(2x - 50) = 180 - (142 + 24)

2x - 50 = 14

2x = 64 ⇒ x = 32

Since, NP = US,

2x - y = 13

2(32) - y = 13

64 - y = 13

y = 51

m∠N = 180° - (142 + 24)°

          = 14°
