Answer 3

How to Expand the Brackets in the Given Example: 5×(9a-4b+c)

To expand the brackets in the given example 5×(9a-4b+c), you can use the distributive property of multiplication over addition and subtraction. This property states that for any real numbers a, b, and c:

a × (b + c) = a × b + a × c a × (b - c) = a × b - a × c

So, applying this property to the given example:

5×(9a-4b+c) = 5×9a - 5×4b + 5×c

Therefore, the expanded form of 5×(9a-4b+c) is 45a - 20b + 5c.
