Simplify #20 - (2 * 4f) + (2 * 9) + (7 * 2f) - (7 * 6) + 11#?

Answer 1

#6f + 7#

Initially, enlarge every term enclosed in parenthesis, paying special attention to the indicators inside and outside the parenthesis:

#20 - (2*4f) + (2*9) + (7*2f) - (7*6) + 11#

20 - 8f + 18 + 14f - 41 + 11#

We can then group terms like this:

#-8f + 14f + 20 + 18 - 42 + 11#

We can now combine similar terms:

#(-8 + 14)f + 7#

#6f + 7#

To simplify the expression ( 20 - (2 \times 4f) + (2 \times 9) + (7 \times 2f) - (7 \times 6) + 11 ), first, apply the distributive property to the terms with parentheses, then combine like terms: [ = 20 - 8f + 18 + 14f - 42 + 11 ] [ = 20 - 42 + 18 + 11 - 8f + 14f ] [ = -22 + 29 + 6f ] [ = 6f + 7 ]

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
