Answer:
68 square cm
Step-by-step explanation:
Interior square WXYZ is making four right triangles of equal bases (8 cm) and heights (2 cm) inside the square ABCD. Therefore,
Area of shaded Square = Area of square ABCD - 4 times area of one right triangle.

Fifty one is the answer to your question
Answer:
D. 13
Step-by-step explanation:
x = 5
2 x 5 + 3 = 13
5 + 8 = 13
meaning the side length has to be 13, also.

Answer:
9. Always true
10. Always true
11. Never true
12. Always true
13. Always true
14. Never true
Step-by-step explanation:
An inverse is defined as the reflection across the line y=x. Algebraically this means that x and y switch place in the inverse equation and in the coordinate points of a function.
A line will always give a line.
Example: y = 2x -2
Inverse: x = 2y -2 which when rearranged is y = 1/2 x +1.
This also means that the slope if greater than 1 for the function will have a slope less than 1 for its inverse.
