How many solutions does 9(z+8)=-9z-72 have

1 solution.

General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define equation

9(z + 8) = -9z - 72

Step 2: Solve for x

Here we see that we will get only 1 solution for z.

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.

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
