For this questions you need to memorize formula of triangle area. for question 5, just substitute the value into the formula. for Q6 you need to use pythagorean theorem formula to find the lenght of each triangle that i already seperated
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?

Answer:
<u><em>Answer is below</em></u>
Step-by-step explanation:
<em><u>-2 ×^2 - 4y +6</u></em>
<em><u>Evaluate simply means to form an idea of something</u></em>
<em><u>So Evaluate for x=−3,y=−2</u></em>
<em><u>−2(−3)2−(4)(−2)+6</u></em>
<em><u>−2(−3)2−(4)(−2)+6</u></em>
<em><u>Answer =−4</u></em>
The answer is 1, anything that is raised to the 0 is always 1
A nonlinear function is a function whose graph is not a line or part of a line. Ex: 2, 5, 7, 9, 19, 28, 30, 31, 50, 55, 56, 57, 60, 70, 75...
