Answer:
3a-21
Step-by-step explanation:
You multiple 3 with the inside of the parenthesis. 3 time a = 3a and 3 times negative 7 is -21
P = 2(L + W)
P = 60
L = 2W - 3
60 = 2(2W - 3 + W)
60 = 2(3W - 3)
60 = 6W - 6
60 + 6 = 6W
66 = 6W
66/6 = W
11 = W <=== the width is 11 ft
L = 2W - 3
L = 2(11) - 3
L = 22 - 3
L = 19 <=== the length is 19 ft
Answer:
36/59 or 0.610
Step-by-step explanation:
P(female and degree)/P(degree)
72/118
36/59
0r 0.610
Awe sorry no one responded quick enough... did u get it tho?
You have to be able to know the appropriate properties or postulates to apply on the angles or segments to simplify them. An example would be the Angle Addition Postulate. This postulates states that the sum of the individual measures of the interior angles is equal to the measure of the included angle. There are still a lot more properties to choose from depending on the situation.
