Simplify into one fraction.start fraction negative 4 x over x plus 7 end fraction minus start fraction 8 over x plus 7 end fraction
A. Start Fraction negative 4 lower x plus 8 over lower x plus 7 End Fraction
B. start fraction negative 4 x minus 8 over left parenthesis x plus 7 right parenthesis squared end fraction
C. Start Fraction negative 4x minus 8 over x plus 7 End Fraction
D. start fraction negative 4 x plus 8 over left parenthesis x plus 7 right parenthesis squared end fraction
C. Start Fraction negative 4x minus 8 over x plus 7 End Fraction
To simplify the expression, let's first find a common denominator for both fractions:
The common denominator is (x + 7). Now, we can rewrite the expression:
(-4x/(x + 7)) - (8/(x + 7))
Now, combine the numerators over the common denominator:
(-4x - 8) / (x + 7)
Thus, the simplified expression is Start Fraction negative 4x minus 8 over x plus 7 End Fraction, which corresponds to option C.
