Answer:
Step-by-step explanation:
In order to find r we have to square both sides of the equation
The *square root* sign cancels out the *squared* sign therefore:
well, if we try to plot and conect them, we will get square, so the answer is d
B²-4ac?
<span>5x²+7x-6 = 0 </span>
<span>the form is ax²+bx+c = 0 </span>
<span>a=5, b=7, c=-6 </span>
<span>The discriminant D = b²-4ac </span>
<span>= 7² - 4(5)(-6) = 49 + 120 </span>
<span>= 169 </span>

Answer:
The value of the length of AC is 14
Step-by-step explanation:
When points are collinear, it simply means that the points lie on the same straight line.
In this question , we have three points which lie on same straight line.
These are points A, B and C with B between A and C.
Thus the length AC can be obtained by adding the length of AB to the length of BC
Mathematically, the value of the length of AC will be 8 + 6 = 14
