A Toblerone chocolate bar comes in a box shaped as a triangular prism. The length of the bar is 21 cm and the
triangular face has a base width of 6 cm, a slant length
of 5cm and a height of 4 cm.
a) Determine how much material is needed to build the
Toblerone box.

(x, y)→(x − 8, y − 7)

step-by-step explanation:

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
