Answer:
282 bulbs
Step-by-step explanation:
Find how many bulbs there were by multiplying 47 by 6
47(6)
= 282
So, in the 47 boxes, there were 282 bulbs
28^2=784
29^2=841
784<830<841
therefore sqrt784<sqrt830<sqrt841
therefore 28<sqrt830<29
Done!
The first x coordinate is given by 0 and the second one is given as j. So the length of the base is j. (Sometimes in math they give letters rather than numbers. And since you know it is an isosceles then the other vertex should be at x-coordinate half j or j/2.
