The answer is C. Circle
Hope this helps :)
There's really no such thing as the value of a triangle.
Every triangle has three sides, three angles, a base, a height, and an area,
and there could be problems that ask us to find any one of those.
Whatever we need to find, the process is always the same:
-- Take the information that's given.
-- Gather up everything you can remember that talks about a relationship
between what you're given and what you need to find.
-- Use them together to find the missing value.
Let F be the father's current age, and E be Evie's current age.
F = E + 36 this is the current relation between the ages
F + 3 = 5(E + 3) this the relationship in 3 year (hence the + 3)
Then solve by substituting one equation into another:
(E + 36) + 3 = 5(E + 3)
E + 39 = 5E + 15
24 = 4E
6 = E
Evie's current age is 6.
The value of f(19) in the given equation is 55.
<h3>What is the function of a linear equation?</h3>
The function of a linear equation illustrates a straight line graph and for a given set of input into the function, there is usually a specific output.
Given that:
We are to find the f(x) = 19.
So;
f(19) = 3(19) - 2
f(19) = 57 - 2
f(19) = 55
