Answer:
sin ^2 x+ cos ^2 x = 1
Step-by-step explanation:
sin^2 x - cos ^2 x sin ^2 x = sin ^4 x
Factor sin^2 x
sin ^2 x ( 1- cos ^2 x ) = sin ^4 x
Using the identity sin ^2 x+ cos ^2 x = 1 written as 1 -cos ^2 x = sin ^2 x
sin ^2 x ( sin^2 x ) = sin ^4 x
sin ^4 x = sin ^4 x

Answer:
60%
Step-by-step explanation:
First subtract Maria's answer by the actual, 40-25= 15
Next you would divide 15 by the actual. 15÷25= .6
times that by 100 to get .60×100= 60%
The dimensions for the rectangle are 15 by 2.
15 times 2 is 30, which is the area.
15+15+2+2= 34 which is the perimeter
