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.
Answer:
the value of a and b is 68
Step-by-step explanation:
the other half is 224 so you minus 360 from 224 which will give us 136 then you divide by 2 to get a and b.
Answer: Altitudes in a triangle.
Step-by-step explanation:
Just took the test and got it correct.
Mean: 74
(72+72+73+75+78) divided by 5
median: 73
(line all the numbers up in numerical order then cross out one from each side and repeat process until in the middle)
