Given a rectangle with dimension by . Find the area of the rectangle when and .
Given a rectangle with dimension (2x+y)(2x+y) by (2x-y)(2x−y). Find the area of the rectangle when x=\sqrt{10}mx=10mand y=1my=1m.
Answer:...........m^2m2.
HELP ME!!!!!!!!!!!!!!!!!!!!!!!!!
Expan \(\left(2x-y\right)\left(2x+y\right)\)using the FOIL Method.
Apply the distributive property.
\(2x\left(2x\right)+2xy-y\left(2x+y\right)\)
Apply the distributive property.
\(2x\left(2x\right)+2xy-y\left(2x+y\right)\)
Apply the distributive property.
\(2x\left(2x\right)+2xy+\left(-y\left(2x\right)-yy\right)\)
Remove parentheses.
Simplify and combine terms.
Simplify each term.
Move x:
\(2\left(2\left(xx\right)\right)+2xy-y\left(2x\right)-yy\)
Use the power rule \(a^ma^n=a^{m+n}\)to combine exponents.
Add 1 and 1 to get 2.
\(2\left(2x^2\right)+2xy-y\left(2x\right)-yy\)
Multiply 2 by 2 to get 4.
\(4x^2+2xy-y\left(2x\right)-yy\)
Multiply 2 by -1 to get -2
\(4x^2+2xy-y\left(2x\right)-yy\)
Move y:
\(4x^2+2xy-2yx-\left(yy\right)\)
Use the power rule \(a^ma^n=a^m+a^n\) to combine exponents.
\(4x^2+2xy-2yx-y^{1+1}\)
Add
1 and 1 to get 2.
\(4x^2+2xy-2yx-y^2\)
Subtract 2yx from 2xy to get 0.
Move y:
\(4x^2+\left(2xy-2yx\right)-y^2\)
Subtract 2yx from 2xy to get 0.
\(4x^2+0-y^2\)
Add 4x2 and 0 to get 4x2.
\(4x^2-y^2\)

Một hình chữ nhật với chiều dài và một nửa chiều rộng. Nếu mỗi chiều được thêm hình chữ nhật mới có diện tích 64m2 2m bổ sung. Tính diện tích hình chữ nhật ban đầu? Tick cho tớ nhé. Lời giải thì chưa có.
the area of the rectangle is x if the length of the rectangle is increased by 20% and the width of the rectangle is decreased by 10%, the area of the rectangle is increased by 20 m2 find x
the area of the rectangle aftter the length of the rectangle is increased by 20% is :
\(x.\left(100\%+20\%\right)=x.120\%\)
the area of the rectangle aftter the width of the rectangle is decreased by 10% is :
\(x.120\%.\left(100\%-10\%\right)=x.120\%.90\%=x.108\%\)
so the area of the rectangle is increased by 20 m2 equivalent \(x.8\%\)
\(\Rightarrow x=20:8\%=250\)m2

diện tích hình chữ nhật là x nếu tăng chiều dài 20% và giảm chiều rộng 10% thì diện tích hình chữ nhật tăng thêm 20 m2 tìm x
The area of a rectangle increased by 57cm2 when each side increases by 3cm.The perimeter of the original rectangle is .... cm.
=32 cm
