What is the discriminant of 3x2 - 10x = -2?
76
94
106
124

Option A.

Step-by-step explanation:

The given equation is

It can be rewritten as

If a quadratic equation is , then discriminant is .

In the given equation a=3, b=-10 and c=2. So, the value of discriminant is

Therefore, the correct option is A.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
