If △ A B C △ ⁡ A ⁣ B ⁣ C uses a sequence of transformations to move, which of the following would NOT guarantee that it would map onto △ D E F △ ⁡ D ⁣ E ⁣ F proving △ A B C ≅ △ D E F △ ⁡ A ⁣ B ⁣ C ≅ △ ⁡ D ⁣ E ⁣ F ?

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

ask the math teacher she or he would know lol.
