Step-by-step explanation:
what number do you need to know
Answer:
2x^2-3x-5=y
(2x-5)(x+1)=y
(2x-5)(x+1)=0
2x-5=0
2x=5
x=2.5
x+1=0
x=-1
Have a great day!
Step-by-step explanation:
It is a triangle where all the angles are acute.
An acute angle is an angle measuring less than 90 degress.
Note that, since the sum of the interior angles of a triangle is 180, a triangle can have at most one non-acute triangle. In fact, if a triangle had two angles, and both exceeding 90 degrees, their sum alone would exceed 180 degress, which is impossible.
