Rewrite the expression 14m - (5+8m) without parentheses

Step-by-step explanation:

14m - (5+8m) = 14m - 5 - 8m

                     = 14m - 8m - 5

                     = 6m - 5

Step-by-step explanation:

The question above is answered below.

Rewriting the expression above without parentheses is done by simply removing the parentheses using the negative sign. Note that the signs of the constant (5) and term (8m) in the expression are positive (+). Thus, using the negative sign to remove the parentheses will be done using the arithmetic signs rule: - × + = -, that is, minus times plus equals minus; such that - × +5 = -5 and - × +8m = -8m. Therefore,

In case the expression is to be evaluated, the result will be:

14m - 5 - 8m

Rearrange the terms

14m - 8m - 5

6m - 5

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
