Step-by-step explanation:
the area of this rectangle is
(10 + 2x)(8 + 2x) = 168
80 + 20x + 16x + 4x² = 168
4x² + 36x = 88
because for the whole length you need to add x twice (left and right). the same for the width (top and bottom).
Answer:
A = 1863
Step-by-step explanation:
There are a few ways you could do this but I will do the one I know best.
Keep in mind the area is the L(enght x W(idth) = A(rea)
There are two long rectangles if you cut off the square in the middle so find the area of those two first.
31 x 23 = 713
713 x 2 = 1426 (Did this to get the area for both of them.
Now find the area of the square.
23 x 19 = 437
The you would add them all up together to get 1426 + 437 = 1863
Hope this helps :)
Answer:
The answer is 1/x-3
Step-by-step explanation:
2/x−3+3/x+2−(4x−7/x2−x−6)
=x+2/x²−x−6
=x+2/(x+2)(x−3)
=1/x−3
Answer:
$48.35
Step-by-step explanation:
