sweet-ann [11.9K]4 years ago
6 0
<h3>Answer:</h3>

A, F

<h3>Step-by-step explanation:</h3>

When the roots are a and b, the factors are (x-a) and (x-b). For roots -20 and 9, the factors are (x+20) and (x-9).

This selects answer A and eliminates choices B and C.

___

Multiplying the two factors gives ...

... (x +20)(x -9) = x² +11x -180

This selects answer F and eliminates choices D and E.

Can Someone Help Me Please????
crimeas [40]

The theorems that apply are A(HL) D(SAS) E(LL)

<h3>What are similar triangles?</h3>

Two triangles are said to be similar if their corresponding angles are equal and their corresponding lengths are in the same proportion.

Analysis:

The two triangles are similar according to the HL theorem since the hypotenuse of the two triangles are equal and one of the sides is same in both triangles. HL theorem applies.

The two triangles are similar according to LL theorem since the other lengths apart from the hypotenuse are also equal.

since two sides of both triangles are equal and there is an included angle 90 degree between the equal sides, the triangles are similar based on SAS.

What is the value of n?
sergij07 [2.7K]
The answer is 95. The angles should equal 360. Add the given two angles and subtract from 360. 360-265=95. So the third angle is 95. Hope I was able to help.

The functions of f(x) and g(x) are shown on the graph f(x)=[x] what is g(x)?
ZanzabumX [31]

Answer:

The answer is option D

g(x) = |x+3|

Step-by-step explanation:

Please see attached graph

The changes made to the function result from translating the graph of f(x) three units to the left

By substituting the equations provided at x = -3 and x = 0 respectively, we can find the same value for both functions.

g(x = -3) = |(-3)+3| = |0| = 0

f(x = 0) = |0| = 0
