Step-by-step explanation:
sin(theta)÷costheta+sintheta/sintheta÷COStheta- sintheta
sintheta+sintheta×costheta/sintheta-sintheta-costheta
sintheta(1+Costheta)/sintheta(1-costheta)
1+1÷Sectheta/1-1÷Sectheta
sectheta+1÷sectheta/sectheta-1÷sectheta
sectheta+1/sectheta-1
Answer:
A rational expression is a ratio of two polynomials. The domain of a rational expression is all real numbers except those that make the denominator equal to zero.
Step-by-step explanation:
3/8x+1=9/4
3/8x=9/4 -1
3/8x=1.25
0.375x=1.25
x=3.333
Answer:
the answer is B
