Step-by-step explanation:
Answer:
Part a) The quadratic function is 
Part b) The value of x is
Part c) The photo and frame together are
wide
Step-by-step explanation:
Part a) Write a quadratic function to find the distance from the edge of the photo to the edge of the frame
Let
x----> the distance from the edge of the photo to the edge of the frame
we know that

Part b) What is the value of x?
Solve the quadratic equation 
The formula to solve a quadratic equation of the form
is equal to
in this problem
we have

so
substitute in the formula

-----> the solution
Part c) How wide are the photo and frame together?

If the triangle is an equilateral triangle, then all three angles are exactly 60 degrees each. A right-angled triangle has one angle of 90 degrees, which is the right angle, with two more angles that total 90 degrees when added together.
Answer:
all are "yes"
Step-by-step explanation:
A polynomial is defined for all values of x. None are excluded. Every value listed is in the <em>domain</em> of f(x) = (x +1)².
