Answer:
36
Step-by-step explanation:
You subtract 180 from 56 then add your answer, 124 to 20, then subtract 144 from 180 to get 36
X^2 + 2x = -1......take half of ur x term (2x), and square it. So we take half of 2, which is 1, and square it....1^2 = 1....so u would add 1 to both sides
The average can be calclculated as follows:
average = sum of number/number of numbers
average = (19+45) / 2 = 64/2 = 32
