Answer:
the parentheses say that you have to multiply -5 and 2
where as -52 is just a number.
The answer is 12y+30.
Twice the width would be 10+4y, so the length is 10+4y.
To find the perimeter, we can do 2(5+2y) + 2(10+4y).
That equals 10+4y+20+8y.
Which, equals 12y+30.

Step-by-step explanation:
Answer: the answer is 12 cm
let's recall on the Unit circle that, as the angle opens opens opens, the "y" value goes up up reaches 1, the as the angle continues it goes back down down and so on.
to make it short, sin(θ) just as cos(θ) will always spit out a value that is either -1 or 1 or anywhere in between, thus their range is -1 ⩽ sin(θ) ⩽ 1.
