Answer:
I don't know what is this
72 because right number on the top of the bar is six, and 12•6=72
5t = 25+2r
t = (25+2r)/5 or
t = 5 + (2/5)r
Answer: x - 5/x + 1
Step-by-step explanation:
This algebraic fraction
The task to be performed here is factorisation and simplification. Now going by the question,
x² + 4x - 45/x² + 10x + 9, the factorisation of
x² + 4x - 45 = x² + 9x - 5x - 45
= x(x + 9 ) - 5(x + 9 )
= ( x + 9 )(x - 5 ), don't forget this is the algebraic fraction's Numerator
The second part
x² + 10x + 9 = x² + x + 9x + 9
= x(x + 1) + 9( x + 1 )
= ( x + 9 )( x + 1 ), this is the algebraic denominator.
Now place the second expression which is the denominator under the first expression which is the numerator.
( x + 9 )( x - 5 )/( x + 9 )( x + 1 ).
You can see that, ( x + 9 )/( x + 9 ) divide each other , therefore therr then cancelled and left with
x - 5/x + 1
Answer:
4
Step-by-step explanation:
5(x + 1) -x = 17 Distribute the 5
5x + 5 - x = 17 Combine like terms
4x + 5 = 17 Subtract 5 from both sides
4x = 12 Divide both sides by 4
x = 3
Three is the smaller integer and 4 is the greater integer.
