Answer:
-50x^2+30x-4
Step-by-step explanation:
35*75 is
2625
2625/400 is
6.5625
Since you cannot have a decimal amount of a bag, you should purchase
(rounding)
7 bags of fertilizer
A: (x + 5i)^2
= (x + 5i)(x + 5i)
= (x)(x) + (x)(5i) + (5i)(x) + (5i)(5i)
= x^2 + 5ix + 5ix + 25i^2
= 25i^2 + 10ix + x^2
B: (x - 5i)^2
= (x + - 5i)(x + - 5i)
= (x)(x) + (x)(- 5i) + (- 5i)(x) + (- 5i)(- 5i)
= x^2 - 5ix - 5ix + 25i^2
= 25i^2 - 10ix + x^2
C: (x - 5i)(x + 5i)
= (x + - 5i)(x + 5i)
= (x)(x) + (x)(5i) + (- 5i)(x) + (- 5i)(5i)
= x^2 + 5ix - 5ix - 25i^2
= 25i^2 + x^2
D: (x + 10i)(x - 15i)
= (x + 10i)(x + - 15i)
= (x)(x) + (x)(- 15i) + (10i)(x) + (10i)(- 15i)
= x^2 - 15ix + 10ix - 150i^2
= - 150i^2 + 5ix + x^2
Hope that helps!!!

Answer:
Step-by-step explanation:
Given that your friend tossed a fair coin when you weren’t around.
Let A be the event that she said the outcome is head
B1 = Event she lied and B2 = Event she did not lie
P(AB1) = 
P(AB2) = 
Required probability = P(B1/A)=
