Answer:
Area of the picture is 
Step-by-step explanation:
Given:
Outer rectangle dimensions are 10 cm by 12 cm.
Inner rectangle dimensions are 6 cm by 8 cm.
Area of the picture given as:

Outer rectangle area = 
Inner rectangle area = 
Therefore, the area of the picture is given:

Answer:
x=8
Step-by-step explanation:
The exterior angle of the triangle is equal to the sum of the opposite interior angles
11x+2 = 6x+2 + 40
Combine like terms
11x+2 = 6x+42
Subtract 6x from each side
11x+2-6x = 6x+42-6x
5x+2 = 42
Subtract 2 from each side
5x+2-2 = 42-2
5x = 40
Divide each side by 5
5x/5 = 40/5
x = 8
Once you have it in that form, you just read off the values of h and k
For instance, if you had y = 2(x-3)^2 + 5, then h = 3 and k = 5. So the vertex is (h,k) = (3,5)<span />
