Answer:
Tn=6n+15
Step-by-step explanation:
Tn=6n+15
T9=6*9+15
T9=54+15
T9=69
Answer:
Length=8 m,Breadth=6 m,Height=3 m
We know,
LSA=2(l+b)×h
LSA=2×14×3=84 m
2
Therefore, cost of painting = 84×60=Rs.5040.
59 kilometers because 110/110 is equal to 59/59
Answer:
x = (5,3)
Step-by-step explanation:
the quadratic formula is x =( -b±√(b^2-4ac))/2a
to solve for x, a=1, b=-8,c=15
x =( -(-8)±√((-8)^2-4*1*15))/2(1)
x=8 ± √(64-60))/2(1)
x=(8 ± √(4)) / 2
x=(8 ± 2) / 2
solve with '+'
x=(8 + 2) / 2 = 10/5 = 5
solve with '-'
x=(8 - 2) / 2 = 6/2 = 3
x = (5,3)
