Assuming no snow was melting, how much snow would Elizabeth have on her lawn 4 hours after the snow began to fall?
We know she started with 8 inches
We also know that every hour an inch of snow falls.
Time 1inch by 4 hours =4inches
Add them together
8inch+4inch=12inch
I'm assuming that there is another root which should be -SQRT(11)
f(x) = x(x-4)(x+SQRT(11))(x-SQRT(11)
Then
f(x) = x^4 -4x^3 - 11x^2 +44x
Multiplying everything and combining if needed, the product is, 15a^5b^15

Answer:
The answer to your question is Angelica 19, her mom = 11
Step-by-step explanation:
Data
Angelica has 8 more than her mother
total number of shoes = 30 pairs
The Number of pairs Angelica has = a = ?
The Number of pairs her mother has = m = ?
Process
1.- Write two equation that help to solve this problem
a = m + 8 Equation l
a + m = 30 Equation ll
2.- Solve the system of equations by substitution
Substitute equation l in equation ll
(m + 8) + m = 30
-Solve for m
m + 8 + m = 30
2m = 30 - 8
2m = 22
m = 22/2
m = 11
3.- Find a
a = 11 + 8
a = 19
4.- Conclusion
Angelica has 19 pairs of shoes and her mom has 11
