Evaluate the expression 3x plus z plus 2y -12 if x equals 3y equals eight and z equals five

Hey there!

3x + z + 2y - 12

We know this information:

x = 3

y = 8

z = 5

With this information, we’ll just “fill in the blanks” (aka the parts with the exponents)

So, the expression would look like this:

(3 * 3) + 5 + (2 * 8) - 12

Now, we solve (see photo)

Therefore, the answer is 18

Hope this helps you!

God bless ❤️

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

practice. practice. practice.
