Answer:
C
Step-by-step explanation:
x²-14x-49=0
x²-14x+49=49+49
(x-7)²=98
(x-7)²=49×2
x-7=±7√2
x=7+7√2=7(1+√2)≈7(1+1.414)≈7(2.414)≈16.898≈16.9
or
x=7-7√2=7(1-√2)≈7(1-1.414)≈-7×0.414≈-2.898≈2.9

It is number four
Step-by-step explanation: when you have a dividing one such as this you subtract the exponents which would give you 9^-5 but you can’t have a negative so make a fraction and its a positive
Answer:
The distance between the givens points is 9 unit
Step-by-step explanation:
Given points are as :
A = ( 1 , 5 )
B = ( 1 , - 4 )
So, The Distance between points A and B = AB
Now, From Distance formula
AB = 
Or, AB = 
Or, AB = 
Or, AB = 
= 9
Hence The distance between the givens points is 9 unit Answer
It would be D 2 if you take each placement of dots and find the differ by multiply or divide that should get you the other hard to explain but ya
