Answer:
i have no idea
Step-by-step explanation:
1st Number = A
2nd Number = B
3rd number = C
4th number = D
5th number = E
A=B² ( first number
is the square of the 2nd number)
B+C=10 ( Sum of 2nd and 3rd = 10)
C=10-B = B=10-C (10-(10-B) equals B (2nd Number)
D=B+1 (4th number = 2nd number + 1)
E=14-C (5th number minus 3rd number = 14)
Add them together to equal 30
B²+B+(10-B)+(B+1)+(4+B)=30
B²+B+10-B+B+1+4+B=30
B²+B+10+1+4+B=30
B²+2B+15=30
B²+2B-15=0
B²+5B-3B-15=0
(B²+5B)-(3B-15)=0
B(B+5)-3(B+5)=0
B-3=0 or B+5=0
B=3
The second number (B) = 3
1st number is 3² = 9
2nd number is B = 3
3rd number is 10-B = 7
4th number is B+1 = 4
5th number is 14-third number = 7
9 + 3 +7 +4 + 7 = 30
