Remove the parentheses from the following expression: (+6) – (+2)
a. –6 – 2
b. 6 – 2
c. –6 + 3
d. 6 + 2

B. 6-2

Step-by-step explanation:

We have been given expression :

Now we need to rewrite that expression , without parenthesis then select which of the given choices are correct.

We know that product of opposite sign is always negative sign.

Then product of - and +2 gives -2

So we can rewrite the problem as:

Hence choice B. 6-2 is the final answer.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
