Answer:
x = +/-10°
Step-by-step explanation:
[2(x+10)]°=
[2x + 20] =
[2x] = [-20]
2x/2 = -20/2
x = -10
(3x - 30)°
3x/3 = 30/3
x = 10
total length = total perimeter of dance floor
20 x 2 + 30 x 2 =
40 + 60 =
100 feet

<h2>A≈1385.44</h2>
A= π r^2 = π*21^2 ≈ 1385.44236
Answer:
The range is from -6 to 4 (inclusive).
The range is the set of y values for which the relation exists.
Looking for bottom to top the curve exists everywhere from y=-6 (lowest y) to y=4 (highest y).
The range is [-6,4] in interval notation.
The range is
in inequality notation.
