Hey !!!
sinx = 3/5 ( given )
We know a formula of cos2x = ( 1 - 2sin²x)
putting the value of sinx on value of cos2x = ( 1 - 2sin²x)
hence,
we get
cos2x = ( 1 - 2sin²x )
=> [1 - 2 × ( 3/5 )² ]
=> [ 1 - 2 × 9 /25 )
=> [ 25 - 18 /25 ]
=> 7/25 Answer ✔
The answer is 1.048576 x 10 to the 6th power.
3(a + b) and 3a + b - NOT EQUIVALENT because
3(a + b) = 3a + 3b
<em>used distributive property a(b + c) = ab + ac</em>
4(x + 2y) and 8y + 4x - EQUIVALENT because
4(x + 2y) = (4)(x) + (4)(2y) = 4x + 8y = 8y + 4x
<em>used distributive property a(b + c) = ab + ac</em>
<em>and commutative property a + b = b + a</em>
