Answer:
10x - 4y = 16
Step-by-step explanation:
2(5x - 2y = 8)
10x - 4y = 16
A^2 - b^2 = (a - b)( a +b);
<span>cos^4x-sin^4x =( cos^2x + sin^2x )( cos^2x - sin^2x) = 1* cos2x = co2x.</span>
13*2
26*1
52/2
There are three ways to make 26
1st perinthesis: 3/4 - 1/4 = 2/4 = 1/2
15/24 - 10/24 =5/24
5/24(1/2) = 5/48
5/48 + 32/48 = 37/48
so the answer is 37/48
