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.

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
