Just try it like this. Hope it helps
In triangle ABC and DEF
AC =DF, [ given ]
AB =DE, [ given ]
angle A = angle D
by SAS
ABC congruent to triangle DFE
so
BC = EF, [ CPCTC]
hence proved
Answer:
Option C
Step-by-step explanation:
Given : Astronomers measure large distances in light years. One light-year is the distance that light can travel in one year or approximately 5,880,000,000,000 miles.
Suppose a star is 14.4 light years from earth.
To find : How many miles away a star is from earth?
Solution :
In 1 light-year the distance a light can travel is = 5,880,000,000,000 miles.
or = miles
In 14.4 lights year the distance is
or
Therefore, Option C is correct -
Answer:
3.3776997 x 10¹² inches high
Step-by-step explanation:
The number of sheets obtained after each tear (N) is described by an exponential relationship, where 'n' is the number of tears:
For n = 50:
If each sheet is 0.003 in thick, the stack would have a height of:
The final pile would be 3.3776997 x 10¹² inches high.
Answer:
x^3 - 5x^2 + 2x + 8
= (x^3 - 4x^2) - (x^2 - 4x) - (2x - 8)
= x^2(x - 4) - x(x - 4) - 2(x - 4)
= (x^2 - x - 2)(x - 4)
= [x(x - 2) + (x - 2)](x - 4)
= (x - 2)(x + 1)(x - 4)
Hope this helps!
