The radius is 10, so the diameter is 20. This means the parts of the diameter (the chord through the center P) to the left and right of the vertical chord have lengths 16 and 4, respectively.
Because the horizontal chord is a diameter, the vertical chord is cut in half, so its parts above and below the diameter both have length <em>x</em>.
Now, by the intersecting chord theorem,
16×4 = <em>x</em> × <em>x</em>
or
<em>x</em> ² = 64
so that
<em>x</em> = 8
8x-19=-3x-41
+3x +3x
11x-19=-41
+19 +19
11x=-22
÷11 ÷11
x=-2
For example, if we use 5+3=8.
If you change it to 3+5, it still equals 8.
Therefore, 3+5=5+3 because at the end, they both have equal value aka both end up with 8 using the same numbers. (goes by the rule a+b=b+a)
Answer:
p=number of seashells pierre collected
p+3p=52
4p=52
p=13
13 seashells
Basically, what you will do is 540 divided by 6
When you divide that, you should get, 90 parcels.
Hope this helps! Have a good rest of your day! c:
