Evaluate the following expression using the values given: find 2x − 3y − z if x = −2, y = 3, and z = −2 a −11 b 11 c −15 d 15

Hey there! :) 

2x - 3y - z ; When x = -2, y = 3, & z = -2

Since we're given the values of x, y, & z, we can very simply plug everything in! 

2(-2) - 3(3) - (-2)

Simplify.

(-4) + (-9) + 2

Get rid of parenthesis.

-4 - 9 + 2

Remember to do PEMDAS!

So, since adding comes before subtracting, let's add! :) 

-4 - 9 + 2

-4 - 7

Simplify.

-11

So, our answer is [A] : -11

~Hope I helped!~

Your answer would be ahere is how: perimeter is how long all the sides are. in a rectangle, there are two sets of parallel sides. so, to find this, we would to the following.(15x2)+(4x2)30+838if you have questions ask! and mark me brainliest! i really wanna level up : 3
