Step-by-step explanation:
-27/-3
27/3 is 9
each of them have a negative so it stays positive
9
-2 ,-1,0,1 are the domains
6×(1×5)=(6×1)×5
6×5=6×5

What’s the area of the semi circles and square?
Answer:
x = 13 and y = 13√3
Step-by-step explanation:
Recall that sin Ф = opposite side / hypotenuse, and that
cos Ф = adjacent sice / hypotenuse.
if we recognize that the angle Ф is 30° here, then we know that:
x = opposite side = hypotenuse * sin 30° = 26*(1/2) = 13.
and....
y = adjacent side = hypotenuse*cos 30° = 26*√3/2 = 13√3
In summary, x = 13 and y = 13√3
