Yes, for fractions you can multiply the denominator by the numerator. For square roots you can use the square root button.
Unit rate would be 50 because 250÷5=50, so the answer would be (250×3)+50, witch is 800.
Answer:
LHS.= Sin 2x /( 1 + cos2x )
We have , sin 2x = 2 sinx•cosx
And. cos2x = 2cos^2 x - 1
i.e . 1+ cosx 2x = 2cos^2x
Putting the above results in the LHSwe get,
Sin2x/ ( 1+ cos2x ) =2 sinx•cosx/2cos^2x
=sinx / cosx
= Tanx
.•. sin2x/(1 + cos2x)= tanx

C. Supplementary
This means their angles add up to 180° which is a straight line
