In the given question, it is given that, the cost of telephone call, s, is $0.75 plus $0.25 times the number of minutes .
And we have to put the given informationin algebraic expression .
For the cost of telephone call, we have to use s and for the number of minutes, we need to use t .
So the required expression is
Answer:
1. 10
2. 4, and the bottom row is 21
3. divide the bottom by 4. you get 8
4. top row is 15 and bottom row is missing 6
I am pretty sure the answer is the second option
If it is 5 lawns then an easy way you could do it is dividing 28 and 2, to get 14, then multiply 5 by 14. Or you could set up a proportion which would be 2/28=5/x and solve for x by cross multiplying. The answer you should get out of this is 70 minutes. Or and hour and 10 minutes.
Step-by-step explanation:
=>x⁴-5x²+4
=>x⁴-x²-4x²+4
=>x²(x²-1)-4(x²-1)
=>(x²-1)(x²-4)
=>(x+1)(x-1)(x+2)(x-2)
hope this helps you.
