Step-by-step explanation:
To prove the identity we just manually compute the left hand side of it, simplify it and check that we do get the right hand side of it:
(that's the definition of squaring a number)
(we distribute the product)
(we just use square notation instead for the first and last term)
(since product is commutative, so that ab=ba)
(we just grouped the two terms ab into a single term)
Step-by-step explanation:
88/7 units
Sorry but u should write ur expression so i can solve it....
Is the 2 at the end indicating squared?
If so,
(3n-2m) (3n-2m) = ?
9n-6nm-6nm+4m = ?
9n+4m-12nm = ?
hope this helps!
The answer for this question will be 20 ft
8= 4x2 so 5x4=20ft
