Where you see x, you would substitute for -1. f(-1)= 2(-1) + 2. f(-1)= -2 + 2 =0
THE ANSWER IS C IF I RECALL DOING THIS
Answer:
12
Step-by-step explanation:
divide 28 by 7 giving you 4 then multiple that by 3
Let s represent the measure of the second angle. Then the sum of the three angles of the triangle is ...
... first + second + third = 180°
... 2s + s + (s+72°) = 180° . . . . substitute the given information
... 4s = 108° . . . . . . . . . . . collect terms, subtract 72°
... s = 27° . . . . . . . . . . . . . divide by 4
The first angle measures 54°.
The second angle measures 27°
The third angle measures 99°.
