1st number = n
2nd number = n+1
3rd number = n+2
sum of the squares of 3 consecutive numbers is 116
n² + (n+1)² + (n+2)² = 116
n² + (n+1)(n+1) + (n+2)(n+2) = 116
n² + [n(n+1)+1(n+1)] + [n(n+2)+2(n+2)] = 116
n² + n² + n + n + 1 + n² + 2n + 2n + 4 = 116
n² + n² + n² + n + n + 2n + 2n + 1 + 4 = 116
3n² + 6n + 5 = 116 Last option.
Step-by-step explanation:
7e=the money she makes from earrings
13n=the money she makes from necklace
The midpoint between these two would be -7, as you would add these two numbers, and then divide by two.
The answer is 4 and 3/8, because if you subtract 5 3/4 from 10 1/8, you'll get your answer: 4 3/8. Hope this helps, and good luck!!
Point B is located at point (4, -2)
