Answer:

Scalene

Step-by-step explanation:

The three angles have different measures, so the sides have different lengths.

Sometimes it's hard not to assume something from a picture.  Just because two of the sides look congruent doesn't mean they are.  The information in the diagram (and geometry knowledge and logic!) are your guide.

What is f(-2) of the function given below? *<br> f(x) = 3x2 - 4x + 1
slava [35]

Answer:

f(-2) = 21

Step-by-step explanation:

Step 1: Define

f(x) = 3x² - 4x + 1

f(-2) is x = -2

Step 2: Substitute and Evaluate

f(-2) = 3(-2)² - 4(-2) + 1

f(-2) = 3(4) + 8 + 1

f(-2) = 12 + 9

f(-2) = 21

What is the solution of StartRoot x + 12 EndRoot = x?
Ber [7]

Answer:

x = 4      or x = -3

Step-by-step explanation:

\sqrt{x+12}=x

Take square both the sides,

(\sqrt{x+12})^{2}=x^{2}\\\\x+12=x^{2}

x² - x - 12 = 0

x² - 4x + 3x - 3*4 =0

x*(x - 4) + 3*(x - 4)= 0

(x- 4 )(x+3) =0

x -4 =0   or x + 3 = 0

x = 4      or x = -3
