the answer is circle idk if it's right but it could be I'm in high school I've been through algebra 1 now in geometry
Sent a picture of the solution to the problem (s).
Reorder 2 cos (2y) and sin (2y)
= sin (2y)(2 cos(2y))
Remove parenthesis
= sin (2y) * 2 cos (2y)
Reorder sin (2y) and 2
= 2 * sin (2y) cos (2y)
Apply the sine double-angle identity
= sin (2(2y))
Now multiply 2 by 2
<u>= sin (4y) </u>
D- 2x-1
plug in a number for x and you'll see
98 is a composite number. 98 = 1 x 98, 2<span> x </span>49<span>, or </span>7<span> x </span>14<span>. Factors of 98: 1, </span>2<span>, </span>7<span>, </span>14<span>, </span>49<span>, 98. Prime factorization: 98 = </span>2<span> x </span>7<span> x </span>7<span>, which can also be written 98 = </span>2<span> x 7².</span>
