Answer:
1/4(n - 64) hope this helps!
Answer:
This polygon is comprised of 30 congruent triangles, each with a central angle of 12°
And using trig, each has an area of......
(1/2)(20)^2 sin(12°) = 41.5823381636 sq ft
So, 30 times this = 1247.470144908 sq ft = 1247.5 sq ft (rounded to the nearest tenth)
Answer:
x=1
Step-by-step explanation:
2x+16-4x=10x+4
-2x+16=10x+4
16-4=10x+2x
12=12x
1=x
The correct answer is 6+x-y.
This is because the other answer choice is a binomial and not a trinomial (which contains three terms). A term is always separated by - or + signs.
