Let's start with 14, shall we? Alright, so we know that positive and negative numbers are both on opposite sides of zero- negatives on the left, positives on the right. We see that we have a positive and negative. That lets us know that we have these two values on opposite sides. As for one, we see that it's (going to assume it's negative, as that's what it looks like. If not, do the same thing on the other side.) 5/8, we can only do fourths here, it seems, because there are four intervals between the numbers. Here's where the beauty of equivalent fractions comes in. 5/8 actually equals 2.5/4 if you divide the top and bottom by 2. Now it should be easy to graph it. A little after 1, and then in between 2 and three. Hope this helps.
Answer:
15
Step-by-step explanation:
The product of distances from P to the two intersection points along the same secant (tangent) is the same for each. For this purpose, the tangent can be considered to intersect the circle twice at the same point. That is ...
PN·PM = PQ²
x(2x +7) = (x +6)²
2x² +7x = x² +12x +36
x² -5x -36 = 0
(x -9)(x +4) = 0 . . . . . . . true for x=9, x=-4
The relevant value of x is 9.
PQ = x +6 = 9 +6
PQ = 15
Answer:
i think the answer is
225 beacuse 15×15=225=r^2
