suter [353]

Answer:

63 weeks

Step-by-step explanation:

252 - 3x = 378 - 5x

+ 5x +5x

Add 5x to both sides

252 + 2x = 378

-252 - 252

Subtract 252 from both sides

2x = 126

Divide 2 from both sides

x = 63

Check you work by plugging 63 where the x is

252 - 3(63)

252 - 189 = 63

378 - 5(63)

378- 315 = 63

Simplify (sinx + cosx) ^2/ sin2x

Aleksandr [31]

$\csc 2x+1$

Step-by-step explanation:

$\frac{(\sin x+\cos x)^2}{\sin2x}$

We expand $(\sin x+\cos x)^2$ using algebraic identity $(a+b)^2=a^2+b^2+2ab$

$=\frac{\sin^2x+\cos^2x+2\sin x.\cos x}{\sin2x}$

$= \frac{1+\sin2x}{\sin2x}$

$=\frac{1}{\sin2x}+\frac{\sin2x}{\sin2x}$

$=\csc 2x+1$
