Solve by factoring. p⁴=-25p²​
3241004551 [841]

Answer:

p=5i

Step-by-step explanation:

(p^(4)=-25p^(2))/p^(2)

p^(2)=-25

Square root both sides

p=5i

i is the square root of -1, so 5i is five times that much.

The square root of a negative number in not real. That is why it is i, and not a number.

A quarter = 25c
A nickel = 5c
A dime = 10c
2 pennies = 2c

25 + 5 + 10 + 2 = 42c

42 divided by 3 is 14 cents
So Willie, Donald and Maya get 14 cents each
