2+2=4
4+2=6
I hope this helps
By the way your X is my C. The Pythagorean theorem is a^2+b^2=c^2. A is 12, and b is 16, you would first plug them in. 12^2+16^2=c^2. So then you square them. You would then get 144+256=c^2. So now you add and get 400=c^2. Now find the square root of both sides to get just c. The square root of 400 is 20 and the square root of c^2 is just c. So that means 20=c or in your case x=20.
<span>1) distance formula; d = √(x2-x1)² +(y2-y1)² . d= √(-4-8)² +(-3-7)² = > d= 2√61
diameter = 2*radius => 2√61 =2r => r =√61 => r² =61
midpoint of the diameter is:
Xm= -4-8 /2 -6 => -6
Ym = -1-9 /2 -5 => -5 center of the cirlce is at (-6,-5)

Millimeter is the smallest and blood cells are really small. I’d say something smaller though, if that’s an option.
