Answer: x = 0
<u>Step-by-step explanation:</u>
4(7 - 3x) = 7(4 - 2x)
28 - 12x = 28 - 14x <em>distributed</em>
28 + 2x = 28 <em>added 14x to both sides</em>
2x = 0 <em>subtracted 28 from both sides</em>
x = 0 <em>divided both sides by 2</em>
Step-by-step explanation:
step 1. The x values refer to the domain of the function.
step 2. if you set y = 0 and solve the quadratic equation the x values refer to the point the graph crosses the x axis.
Looking at this we can group like terms. What are like terms? They are terms that have the same variable that we can add or subtract. In this case the like terms are 6m and m because they both have the same variable and we could add them together to get 7m.
Answer:
Lateral area =
pi * (radius) * √ [ height ^2 + radius^2 ] =
pi * ( 4 ) * √ [ 4^2 + 3^2 ] =
pi * ( 4 ) * √25 =
pi * ( 4 ) * (5 ) =
20 pi units^2 ≈ 62.8 units^2
