Answer:
B. 2x + 4y
Step-by-step explanation:
If x = 4, and y = 7, let's substitute these values for x and y in the equations!
For A, the equation is 2xy. Substitute the values and you have 2(4)(7) which equals 56. This expression is incorrect since the expression doesn't equal 36.
For B, the equation is 2x + 4y. Substitute and you get the equation
2(4) + 4(7) → 8 + 28 = 36.
36 is your desired value, and you get that with the expression 2x + 4y.

Answer:
Below.
Step-by-step explanation:
Convert to sin's and cos's:-
(secx + tanx)(1-sinx)/cosx)
= ( 1/ cos x + sinx / cos x) * ( 1 - sin x )/ cos x)
= (1 + sin x) / cos x) * ( 1 - sin x ) / cos x
= (1 - sin^2 x) / cos^2 x
But 1 - sin^2 x = cos^2 x
so we have
cos^2 x / cos^2 x which = 1.
