Answer:
Step-by-step explanation:
Rewrite this quadratic in standard form: 3x^2 + 7x - 1.
The coefficients of x are {3, 7, -1}, and so the discriminant is b^2 - 4ac, or
7^2 - 4(3)(-1), or 49 + 12, or 61. Because the discriminant is positive, this quadratic has two real, unequal roots
The answer to the question
Answer:
B
Step-by-step explanation:
I think it is three-fifths because the total is 5 and after the A', the length is 3.
So the answer is Three-fifths
Answer:
31
Step-by-step explanation:
Recognize that all angles of a triangle add up to 180 degrees, so your equation would be x + 16 + x + 24 + 78 = 180.
<em>Step 1: Combine like-terms.</em>
2x + 118 = 180
<em>Step 2: Subtract 118 from both sides to isolate the variable.</em>
2x = 62
<em>Step 3: Simplify</em>
x = 31

the rest of them would not make sense plus you have to have brains
