Answer:
Area = 15.36 ft
Step-by-step explanation:
First find the area of the dotted line triangle using the formula: base x height x 1/2, which would be 1.2ft x 12.8 x 1/2 = 7.68ft.
Next, add another triangle at the top, mirroring the shown triangle, of the parallelogram.
Then, find the area of the shape as though it were a rectangle. (base x height) - 2.4 x 12.8 = 30.72.
Next, multiply the area of the invisible triangle by 2, 7.68 x 2 = 15.36ft
and Finally, subtract the area of the rectangle shape of the the sum of the two invisible triangles, 30.72 - 15.36 = 15.36ft
The area of the parallelogram is 15.36 ft.
Answer:
Step-by-step explanation:
6/x^2 + 2 x = 7
2 x^3 - 7 x^2 = -6 (for x!=0)
(2 (x^3 - 3 x^2 + 3))/x^2 = 1
(B+5)(B+5) Is the correct factorization.
If I am correct the answer is 1.
You can do multiply 3 by 6/8 which will give you 2 1/4 or if in a decimal 2.25.
Then do 3 by -1/2 which will give you -1 1/2 and in decimal its -1.5.
You continue with the equation, 2.25 -1.5 = 0.75 + 0.25 = 1
Add them all together and you get 1...!
