Answer:
2x^2*(2x^3+8x^2+2x) or
4x^5+16x^4+4x^3
Step-by-step explanation:
A=[2x^3-x+(8x^2+3x)]*4x^2/2=2x^2*(2x^3+8x^2+2x)
or A=4x^5+16x^4+4x^3
Yes the correct answer is D. Hope this helps :)
Answer:
C. 
Step-by-step explanation:
We proceed to solve for
by the Pythagorean Theorem:
(1)





There are two different solutions:
, 
A solution of
is considered realistic when the length of every side of the triangle is a not negative number.














The only realistic set of solutions is for
, and the radius of the circle is represented by the line segment
: 
And the area of the circle (
) is calculated from the following formula:



The correct answer is C.
Answer:
The area of the figure is equal to 
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The area of the figure is equal to the area of a square plus the area of a triangle
<u>Find the area of the square</u>
The area of square is equal to

<u>Find the area of the triangle</u>
The area of the triangle is equal to

therefore
The area of the figure is equal to
