The answer that you should get is 5(5x^2- 24x +30)
Answer:
In group A, they have at least one 90 degree angle. In Group B, they do not have any 90 degree angles.
Answer:
(-11 +/- sqrt 21) / 10
or
-0.64 , -1.56 to the nearest hundredth.
Step-by-step explanation:
9v^2 + 11v + 5 = 4v^2
5v^2 + 11v + 5 = 0
Using the quadratic formula:
v = [ - 11 +/- sqrt(11^2 - 4*5*5) ] / 2*5
= (-11 +/- sqrt 21) / 10
= -0.64 , -1.56 to the nearest hundredth.
