If a triangle has side lengths of 7 cm, 10 cm, and 12 cm, is it a right triangle ?

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

correct answers below:

the two may have that, even a breakdown is probably offered

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
