Answer:
−25x+54−32rx+64r−x^2
Step-by-step explanation:
(−28−32r−x+1)(x−2)
Add −28 and 1 to get −27.
(−27−32r−x)(x−2)
Apply the distributive property by multiplying each term of −27−32r−x by each term of x−2.
−27x+54−32rx+64r−x^2+2x
Combine −27x and 2x to get −25x.
−25x+54−32rx+64r−x^2
Answer:
1:00 am
Step-by-step explanation: if it is 11:00 add the 5 hours because NYC is 5 hours behind London so when you add them you get to 4:00 am then since Rio is three hours behind you subtract 3 hours from 4:00 am and you get 1:00 am.
Answer:
∠5 = 60°
∠6 = 30°
∠7 = 120°
Step-by-step explanation:
Since the polygon is regular, you know that the central angle (7) is 1/3 of the circle, or 120°. The angle 5 is half that measure, so is 60°, and the angle 6 is the complement of angle 5, so is 30°. (Angle 6 is also half the inscribed angle at each vertex, said inscribed angle being 120°/2 = 60°.)
∠5 = 60°
∠6 = 30°
∠7 = 120°
