Answer:
C
Step-by-step explanation:
Given
=
[ note that ()² = x ]
Square both sides
3x + 8 = 4x + 1 ( subtract 4x from both sides )
- x + 8 = 1 ( subtract 8 from both sides )
- x = - 7 ( multiply both sides by - 1 )
x = 7 → C
Answer:
The original fraction is
Step-by-step explanation:
Let the denominator be x
We are given that The numerator of a fraction (which is in its simplest form) is 5 less than the denominator.
Numerator = x-5
So, Fraction =
If the numerator is multiplied by 2, and the denominator is increased by 16, then the fraction becomes smaller by 1\3 of it.
A.T.Q
x=8
Denominator = 8
Numerator = x-5=8-5=3
Fraction :
Hence the original fraction is
Answer:
Hence as long as x > 2/3, we can form a triangle from the three given sides.
Step-by-step explanation:
Given:
Length of 3 sides of triangle are
Solution:
From the length of the 2nd side 4x, we know that x > 0
Let this be 1 st statement.
Now from the triangle inequality we can say that;
No new information from this because of the 1st statement above.
Also,
Lastly,
and again no new information is obtained from this inequality.
Hence as long as x > 2/3, we can form a triangle from the three given sides.
