Answer:
160 tiles
Step-by-step explanation:
1000cm×900cm=900000cm²
75cm×75cm=5625cm²
900000cm²÷5625cm²=160 tiles
36 is the answer to the question
Answer:
26
Step-by-step explanation:
Answer:
b= 20 • c
b is equalled to how many bottles, which c is equalled to how many cases, since there is no number for how many cases then is just the variable "c".
This is known as quadratic algebra.
To find it, you can use the quadratic formula but that might take a while.
We can factor it out and get
-3(mx² + mx - 1)
We can then set mx² + mx = 1
It would have no solutions
Edit: Above is wrong! I made the mistake of factoring 3 when it cant be factored.
Here is the solution
mx²-3mx=-3
Divide both by -3
mx²+mx=1
And I really messed this up. Its been a long time since quad. Sorry, but I cant seem to get the answer. Try and look up the quadratic formula and see if you can use that
