From one vertex of an octagon you can draw 5 diagonals.
There are 8 vertices in an octagon, and we are choosing one as our starting vertex. There are then 7 vertices left to draw a line to, but 2 of the vertices are already connected to our main vertex (because they are connected along the side of the octagon). That leaves 5 vertices to draw a diagonal to from our original vertex.

Answer:
She used 4 test tubes for the last experiment
Step-by-step explanation:
Total test tubes needed = 14
Experiment 1 = 2 test tubes
Total test tubes remaining = total - used
= 14 - 2
= 12 test tubes
Remaining experiment = 4 - 1
= 3
Test tubes used for the remaining experiment = test tubes remaining / Experiment remaining
= 12 / 3
= 4 test tubes
How many test tubes did she use for the last experiment?

Answer: he needs to buy 578.5 yard² of Sod.
Step-by-step explanation:
Assuming the lawn is square shaped, the formula for determining the area of a square is
Area = length²
If the length of each side of the lawn is 24 1/2 = 24.5 ft
Area of the lawn = 24.5² = 600.25yard²
The area of the pool house is 16yard²
The area of the side walk is
3 × 1 = 3 yard²
The length of the pool is 7 1/2 = 7.5yards
The width of the pool is 2 1/2 = 2.5 yards. Therefore,
Area of pool = 7.5 × 2.5 = 18.75 yard²
Therefore, the amount of Sod that he needs to buy is
600.25 - (3 + 18.75) = 600.25 - 21.75
= 578.5 yard²
Answer: 152
Step-by-step explanation: 19x^2 + 152
19(0)^2 + 152
0 + 152
Ans = 152
