Answer:
x = 5/2 or x = 2.5
Step-by-step explanation:
To solve for x, we will have to get the equation 2x + 15 = 20 into the form x = _. That will be our answer.
2x + 15 = 20
Subtract 15 from both sides to get rid of the +15 on the left side.
2x = 20 - 15
Simplify.
2x = 5
Divide both sides by 2 to get rid of the coefficient of 2 on the left side.\
x = 5/2 = 2.5
x = 5/2 or x = 2.5
I hope you find my answer helpful. :)

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?
