Answer:
x = 7, x = -3
Step-by-step explanation:
We can find the zeros by factoring the equation using the zero product property.
x^2-4x-21 = 0
(x-7)(x+3) = 0
<u>x-7 = 0</u>
x = 7
<u>x+3 = 0</u>
x = -3
Zeros are x=7 and x= -3.
Answer:
x+3

Brian drank 16.72 L of water.
Step-by-step explanation:
Let's set up a ratio that represents the problem:
Liters : Gallon
3.8 : 1
To find how many liters Brian drank, multiply by 4.4 on both sides of the ratio:
Liters : Gallon
3.8 : 1
x4.4 x4.4
16.72 : 4.4
Therefore, Brian drank 16.72 L of water.
