30 = -5(m+6) + m
30 = -5m - 30 + m
0 = -4m
0 = m
D. I think you meant to say 2/3 x so the only correct answer is d
18 groups of 12. 18 times 12. That equals 216. 216 can round to 200, 215, or 220.
Answer:
Step-by-step explanation:
The coefficients of the quadratic x^2 + 7x + 3 are a = 1, b = 7 and c = 3.
The discriminant is b^2 - 4ac, or 49 - 4(1)(3), or 49-12, or 37.
Because the discriminant is positive, we know that this quadratic equation has two real, different solutions.
-7 ± √37
x = --------------- => x = (-7 + √37)/2 and x = (-7 - √37)/2
2
In words: This quadratic equation has two real, unequal solutions involving the radicand 37.
