1 week = $20
1 month= 4 weeks
1 month = (4)(20) ----> $80
12 months = 1 year
12 months = (80)(12) ----> $960
1 year= $960
1800-960 = $840
answer= 1 year 10 months 2 weeks
Answer:
(x + 1)(x - 1) (x- 2)(x - 5)
Step-by-step explanation:
<u>Solving in steps:</u>
- x^4 - 7x^3 + 9x² + 7 x – 10=
- (x^4 - 1 )- (7x^3 - 7x) + (9x^2 - 9) =
- (x^2 + 1)(x^2 - 1) - 7x(x^2 - 1) + 9(x^2 - 1) =
- (x^2-1)(x^2 + 1 - 7x + 9) =
- (x + 1)(x - 1)(x^2 - 7x + 10) =
- (x + 1)(x - 1)((x^2 - 2x) - (5x - 10)) =
- (x + 1)(x - 1) (x- 2)(x - 5)
5+2y=-13+2y5+2y=-13+2y
Y= -40
