1 answer:
professor190 [17]3 years ago
6 0

Answer:

  -2w -14

Step-by-step explanation:

Eliminate parentheses, then combine like terms.

There are no minus signs or other multipliers outside the parentheses, so they can simply be removed.

  2w -9 -4w -5

The "w" terms can be combined, as can the constant terms.

  = w(2 -4) + (-9 -5)

  = -2w -14

Combine the like terms to create an equivalent expression: <br> 2s+(−4s)=?
Sergeeva-Olga [200]

Answer:

2s+\left(-4s\right)=-2s is the equivalent expression as 2s+\left(-4s\right) is equal to -2s.

Step-by-step explanation:

Considering the expression

2s+\left(-4s\right)

As we know that

  • Like terms are said to be the terms which hold the same variables raised to the same power.
  • For example, 3x and 2x are like terms as they contain the same variable x raised to the same power.

Lets solve the expression

2s+\left(-4s\right)

\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a

2s-4s

\mathrm{Add\:similar\:terms:}\:2s-4s=-2s

-2s

Therefore,

2s+\left(-4s\right)=-2s is the equivalent expression as 2s+\left(-4s\right) is equal to -2s.

Keywords: equivalent expression, like terms
