Answer:
-3
Step-by-step explanation:
![6x^2+36x+54=0](https://tex.z-dn.net/?f=6x%5E2%2B36x%2B54%3D0)
First, you can factor out a 6:
![6(x^2+6x+9)=0](https://tex.z-dn.net/?f=6%28x%5E2%2B6x%2B9%29%3D0)
Next, you can factor the quadratic:
![6(x+3)^2=0](https://tex.z-dn.net/?f=6%28x%2B3%29%5E2%3D0)
Since the only value of x that could set this equation equal to 0 is -3, that is the answer. Hope this helps!
Answer:
4 equation 4
Step-by-step explanation:
did math in head
Answer:
the anwers is 5
Step-by-step explanation:
Hello!
4 (x-12) ^ 1/3 = -16
Step 1. Simplify each side of the equation, 4/
3x + −16 = −16 and 4
/3
x −16 = −16
Step 2. Add 16 to both sides, 4
/3
x − 16 + 16 = −16 + 16
Step 3: Multiply both sides by 3/4, (
3/4)*(4/3x)=(3/4)*(0)
Final Answer: x= 0
Hope I could help! :)

linear equation, variables
Step 1
Define the variables
Let
x-----> number of erasers
y-----> total cost
we know that
------> this is the linear equation that represent the situation
therefore
the answer is y = 0.84 + (0.38)x
