Answer: 10 units²
Step-by-step explanation:
We can divide the shape along the y-axis to get 2 separate triangles. If we find the area of each and add them up, we can get the total area of the figure.
We can get each triangle's area using the formula 
<h3>Left Triangle</h3>
base length - 4 units
height - 4 units


<h3>Right Triangle</h3>
base length - 2 units
height - 2 units



Total = 8 units² + 2 units² = 10 units²
Answer:$2800
Step-by-step explanation: Lets first figure out how much money a box of candy bars is worth. We know that each candy bar is worth $5 and that there are 7 candy bars per box. We can multiply 7*5 to figure out that each box is worth $35.
Now lets figure out how many boxes can be sold each day. Each student can sell two boxes a day. 5 students selling 2 boxes each is 5*2= 10 boxes total sold a day.
Now finally we use what we found to figure out the amount of money made per day. We know that there are 10 boxes being sold and that each box makes them $35. We just multiply 10 boxes by $35 to get $350 dollars each day.
Since they sell for 8 days we just multiply 8*$350 to get $2800.
It by root you mean radical equations, well then I can’t help you there, as there is too much stuff to cover.
If you mean zeros, then to find the root of a function you just find the zeros.
