Answer:
Step-by-step explanation:
The side triangles are: 352.35
Middle triangle is: 113.4
352.35 + 113.4 = 465.75
Answer:
y=6x+5
Step-by-step explanation:
I am not sure if this is the answer but it's worth a try...
Part 1We are given

. This can be rewritten as

.
Therefore, a=1, b=-18, c=0.
Using the quadratic formula

The values of x are
Part 2Since the values of y change drastically for every equal interval of x, the function cannot be linear. Therefore, the kind of function that best suits the given pairs is a
quadratic function. Part 3.The first equation is

.
The second equation is

.
We have

Factoring, we have

Equating both factors to zero.

When the value of x is 6, the value of y is

When the value of x is -3, the value of y is

Therefore, the solutions are (6,38) or (-3,11)
