Nothing changes if you don't add anything.
Example:
10+10=20
20+0=20
nothing changes.
Hello :
answer <span>B) 0
because : 4/(5×0) no exist</span>
X-4/2 = 10
x+-2=10
x-2=10
x-2+2=10+2
x=12
Area of a rectangular yard:
A 1 = L x W = 7 x * 6 x = 42 x²
Area of a pool :
A 2 = r² π = ( 2 x )² π = 4 x² π
A = A 1 - A 2 = 42 x² - 4 x² π
The answer must be in terms of π:
B ) 42 x² - 4 x² π
