Use the squared identities to simplify 2sin^2 x cos^2 x

guapka [62]

The given question is

$2sin^2 x cos^2 x$

Multiplying and divide by 2

$\frac{4sin^2 x cos^2 x}{2} =\frac{(2 sinx cos x})^2{2}=\frac{sin^2(2x)}{2}$

Again multiplying and dividing by 2

$\frac{2sin^2(2x)}{4}$

And

$2 sin^2(2x)=1-cos(4x)$

So we will get

$\frac{1-cos(4x)}{4}$

Correct option is D

A rectangle has a perimeter of 124 units. If the length is 5 more than 2 times the width, what is the width.

Fantom [35]

Answer:

19 units

Step-by-step explanation:

Perimeter of the rectangle = 124 units

width = x units

length = 5 + 2x units

The perimeter of a rectangle is given by;

P = 2(l + b)

Substituting values;

124 = 2[(5 + 2x) + x]

124 = 2[5 + 3x]

124 = 10 + 6x

124 - 10 = 6x

114 =6x

x= 114/6

x = 19

width = 19 units
