Answer: The missing number in the sequence is 
Step-by-step explanation:
Since we have given that
First term = a= 
Common difference = d is given by
Therefore, it forms an arithmetic sequence.
Since, 
is missing,
So,
Hence, the missing number in the sequence is
Answer:
-7-√15
Step-by-step explanation:
First move the constant to the right hand side and change it's sign
x^2+14x=-34
Then add (14/2)^2 or 7^2 to both sides
x^2+14x+49=-34+49
Then factor the expression
(x+7)^2=-34+49
Then solve (x+7)^2=15
You should get:
x=-√15-7
or
x=√15-7
The fraction for ur problem would he since 12639 _< 782
Answer:q= -43
Step-by-step explanation:
Step-by-step explanation:
Cost of white shirt=$15
Cost of tie-dye shirt = $20
Total number of shirts= 500
Total number of white shirts= 200
Cost of white shirts = 200×15=$ 3000
Total number of tie-dye shirts = 300
Cost of tie-dye shirts = 300×20= $6000
Verification:
3000+6000=$9000 proved!
