Since 0, -180 is the rotation and if you look at the other rotations like 90, 180 the first rotation would be different. so 0, 180 is the same as 0, -180 because they both would be a full rotation of a 180 rotation. The first number "0 ," would have to be the same.
Answer:
15% markup
Step-by-step explanation:

Product = (7x * 8x) + (7x * 5) + (-4 * 8x) + (-4 * 5) =
Product = 56x2 + 35x - 32x - 20 =
Product = 56x2 + 3x - 20

Answer:
RT=7
Step-by-step explanation:
RS+ST=RT
5x+x+1=5x+2
6x-5x=2-1
x=1
RT=5x+2
RT=7
Answer: 380 ft^2
Step-by-step explanation:
Length of sides of square=25
Diameter of semicircle=25
Radius=r=25/2=12.5
π=3.14
Area of square=length x length
Area of square=25 x 25=625
Area of semicircle=0.5 x π x r x r
Area of semicircle=0.5 x 3.14 x 12.5 x 12.5
Area of semicircle=245.3125
Area of shaded portion=area of square - area of semicircle
Area of shaded portion=625-245.3125
Area of shaded portion=379.6875
Area of shaded portion=380ft^2
