You're being asked to divide 6x^3 - 19x^2 + 16x - 4 by x - 2.
Try using synthetic division, if you know it:
_______________
2 / 6 -19 16 -4
12 -14 4
--------------------------
6 -7 2 0
6, -7 and 2 are the coefficients of the quotient. The quotient (answer to this question) is
6x^2 - 7x + 2
Let me know if you don’t understand anything. Hope this helped.
Answer:
25
Step-by-step explanation:
We can use the is/of=p/100 method for this problem. Since it's 15% off, this would mean that the bill is 85% of what it was initially. Plug the values into the is/of=p/100 formula.
36.72/x = 85/100
Solve for x.
x=36.72/0.85
x=43.2
So, the bill was $43.20 before applying the voucher discount of 15% off.
As we can notice the shape is a Pentagon. A Pentagon's angles should add up to 540. So we can use simple addition and subtraction to solve.
121 + 108 + 102 + 100 = 431
540 - 431 = 109
109 should be your answer
