Answer:  2

<u>Step-by-step explanation:</u>

f(x) = 2x + 3        g(x) = x² - 1

f(g(x)) = f(x² - 1)

         = 2(x² - 1) + 3

         = 2x² - 2  + 3

         = 2x² + 1

The largest exponent is 2 so the degree is 2.

In the diagram AB=AD and
hammer [34]

Answer:

AC ≅ AE

Step-by-step explanation:

According to the SAS congruence theorem, if two triangles have 2 corresponding sides that are equal, and also have one included corresponding angle that are equal to each other in both triangles, both triangles are regarded as congruent.

Given ∆ABC and ∆ADC in the question above, we are told that segment AB ≅ AD, and also <BAC ≅ <DAC, the additional information that is necessary to prove that ∆ABC and ∆ADC are congruent, according to the SAS theorem, is segment AC ≅ segment AE.

This will satisfy the requirements of the SAS theorem for considering 2 triangles to be equal or congruent.
