Let D = discrimination
Rules:
If D > 0, there are 2 real number solutions.
If D = 0, there is only 1 real number solution.
If D < 0, there are 2 imaginary solution.
Given 70w2 - 12w + 1 = 0, b = -12, a = 70 and c = 1.
D = b^2 - 4ac
D = (-12)^2 - 4(70)(1)
D = 144 - 280
D = -136
Our D value is less than 0.
Our case is D < 0.
This means the given quadratic equation has 2 imaginary solutions.
Answer:
There are two real and different roots
Step-by-step explanation:
The discriminant is given by b²-4ac
(-12)²-4(70×1)
144-280
136
Now 136>0
Surface area= 7.5
The area of a triangle is b*h/2. so if you fill in the numbers your equation would be 5*3/2. 5*3=15 and 15/2=7.5
hope this helps!!
(x + 12)(x - 3)
No, he is not correct because red and yellow got the same amount of votes when it came to adding them up.
