Answer:

5

Step-by-step explanation:

To write the polynomial in standard form you need to write it in descending order of degree.

Determine whether the triangles are similar. or not.
mr Goodwill [35]

Answer:

A

Step-by-step explanation:

We know that ∠ABE ≅ ∠DBC because they are vertical angles, so that's one pair of congruent angles. However, we can't compare ∠BAE and ∠DCB as they have different measures, so we'll have to find the measure of either ∠AEB or ∠BDC. Let's go with the former. Using the fact that the sum of the measures of the interior angles of a triangle is 180°, we know that m∠AEB=180-(53+42)=180-95=85°. Now, we know that ∠AEB ≅ ∠DCB because their measures are equal. That's another pair of congruent angles. Therefore, the angles are similar by AA. Hope this helps!

Can you help me on this math problem please?
Nikitich [7]

Answer:

The expression is 1/16 when x = -2, The expression is 64 when x = 3.

Step-by-step explanation:

Part A)

<u>Evaluate 4^x for x = -2. Write your answers in simplest form:</u>

= 4^(-2)

= 1/4^2 ( 1 / 4 * 4)

= 1/16

Part B)

<u>Evaluate 4^x for x = 3. Write your answers in simplest form:</u>

=4 ^ 3

= 4 * 4 * 4

= 16 * 4

= 64

<em>I hope this helps! Make sure to give me the brainliest answer since it is great appreciated. Thank You!</em>
