Charlie did not meet his goal because he used more than 50 gallons per day.
Step-by-step explanation:
Let, x be the number of gallons.
Charlies goal is to use less than 50 gallons of water per day.
x < 50
Gallons used in a month= 1524 gallons of water
Time = 30 days
Gallons used per day = 
Gallons used per day = 50.8 gallons per day.
Charlie did not meet his goal because he used more than 50 gallons per day.

Answer:
D. Undefined
Step-by-step explanation:
The slope is the ratio of rise to run. When the line is vertical, the run is zero, so calculating the slope involves division by zero. That makes the slope be <em>undefined</em>.
Answer: 22 degrees
Step-by-step explanation:
Since the angle 180° is in the third quadrant, subtract 180° from 202°.
Hope it cleared your doubt.
Factor by grouping.
0 = (x^3 +4x^2) +(9x +36) = x^2(x+4) +9(x+4) = (x^2+9)(x+4)
The first factor is the difference of squares (in complex numbers), so the form for factoring that can be used:
a^2 - b^2 = (a -b)(a +b)
Here, a=x, b=3i.
Then the factorization in complex numbers is
0 = (x -3i)(x +3i)(x +4)
Solutions are the values of x that make these factors be zero.
x = -4, -3i, 3i
