I think your diagram had an error because the instruction says that it is a SQUARE frame with sides that are 8 inches long.
Anyways, following the question, the area of the shaded parts should be:
2(8 x 2) + 2(8 - 2 - 2)(2)
= 32 + 16
= 48 sq in.

Answer:
x = 36 and y = 72
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
y is an external angle to the triangle on the right, thus
y = 2x
The sum of the 3 angles in a triangle = 180
Consider the triangle on the left. then
x + 2y = 180 ← substitute y = 2x
x + 4x = 180
5x = 180 ( divide both sides by 5 )
x = 36 and y = 2x = 2 × 36 = 72
Answer:
The possible values for x are 4 and 0.25.
Step-by-step explanation:
In order to solve for "x" in the equation we first need to sum "x" and "1/x", to do that we must apply LMC as shown below:
x + 1/x = 17/4
(x² + 1)/x = 17/4
4*(x² + 1) = 17*x
4*x² + 4 = 17*x
4*x² + 4 - 17*x = 0
4*x² - 17*x + 4 = 0
x = [-(-17) + sqrt((-17)² - 4*(4)*(4))]/(2*4) = 4
x = [-(-17) - sqrt((-17)² - 4*(4)*(4))]/(2*4) = 0.25
The possible values for x are 4 and 0.25.
