Answer:
See below
Step-by-step explanation:
A 30° angle is measured 30° counterclockwise while a -30° angle is measured 30° clockwise. Therefore, you can say -30°=360-30°=330° because 30° is a reference angle located in Quadrant IV.
Since a fraction is a form of division, you do 21/2=10 and 1/2.
Answer:
B and E
aka
E-F and E-D
C-B and C-D
Step-by-step explanation:
Answer:
A = x^2 + 4x -21
Step-by-step explanation:
L = x+7
W = x-3
A = L*W
A = (x+7)(x-3)
A = x^2 + 4x - 21
5/12 - 4/5 = -23/60. You can't simplify -23/60. Hope this is right
