a quadrilateral has 4 angles that add up to 360 degrees
x + 80+110+ 75 = 360
combine like terms
x + 265 = 360
subtract 265 from each side
x + 265 -265 =360 -265
x = 95
Choice C
X^2+5x=2
you then solve by completing the square using the formula (b/2)^2 in order to create the new term. Solve for x by using this term to complete the square.
Your answer is then
x=-5/2+-√33/2
Using proportions, it is found that the Customer Acquisition Cost was of $1,215.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount.
In this problem, the customer acquisition cost is the spending in sales divided by the number of customers added.
80 customers were added, considering costs of 1200 + 9000 + 87000 = $97,200, hence:
97200/80 = $1,215.
