Simplify the expression: 3p+–p

2 answers:

Answer:

$2p$

Step-by-step explanation:

$3p + (-p) \\= 2p$

If you do have a calculator just enter this:

3 + (-1)

I took off the p that was connected to 3 and replaced the -p to become a -1 because a regular p is equal to 1. I added parenthesis because their is a addition (+) and substration (-) next to each other, and the negative (-) sign is a part of the variable p.

Which is the value of this expression when j = negative 2 and k = negative 1?

Natalija [7]

Answer:

Option A.

Step-by-step explanation:

It is given that

$j=-2, k=-1$

The given expression is

$\left(\dfrac{jk^{-2}}{j^{-1}k^{-3}}\right)^3$

Substitute the given values in the above expression.

$\left(\dfrac{(-2)(-1)^{-2}}{(-2)^{-1}(-1)^{-3}}\right)^3$

$\Rightarrow \left(\dfrac{(-2)(1)}{\dfrac{1}{-2}(-1)}\right)^3$

$\Rightarrow \left(\dfrac{-2}{\dfrac{1}{2}}\right)^3$

$\Rightarrow \left(-4\right)^3$

$\Rightarrow -64$

Therefore, the correct option is A.
