The root of an equation f(x) is the x value(s) for which f(x) = 0.
So, if you have f(x) = 6x + 3, to find its root(s), you do 0 = 6x + 3, and then
0 - 3 = 6x + 3 - 3
-3 = 6x + 0
-3 = 6x
-3/6 = 6x/6
-1/2 = x
x = -1/2 is the one and only root (Linear functions will always have 0 or 1 root. They will have zero roots if they are horizontal lines of the form y = c, where c is any constant, and they will have one root if they are of the form y = mx + b, where m is not 0.)
Answer:
300
Step-by-step explanation:
a triangle has 3 sides and so perimeter is just adding all the sides together so the perimeter is 30 that means each side is ten so multiply those all by ten as it says and then they are all 100. add them to get 300, hope this helps :)
