Answer:
A. 6c = t
Step-by-step explanation:
- 6 c- chairs for each table.
- for example
- 3 table, so 6 chairs for each table 3 * 6 = 18.
2. 18 chairs for 3 tables.
Answer:
17
Step-by-step explanation:
(7, 8) (-8, 0)
First find how much the point moved in y to the second point.
8-0=8
So one side is 8.
Then find how much it moved in x. 7-(-8)=15
So the other side is 15
This will give you 2 sides of a triangle where one sides lenght is 8 the other is 15. Use the pythagoras theorem which is x squared plus y squared = c squared
8^2+15^2=c^2
64+225=c^2
289=c^2 Take the square root of both sides to solve for C
√289= √C^2
17 = c
We just check on the graph and see that
the answer is x = -7 and x = 2
