Answer:
3x^4-13x^3-x^2-11x+6
Step-by-step explanation:
Checked this on a website for you btw!
The rule for the area of a polygon is as follows:
Area of a Polygon = Apothem x Perimeter ÷ 2
So, add all the of the outside measurements together to find the Perimeter but I don't know where the Apothem in the polygons are.
I hope this gives you some sort of a lead. :)
To answer the question, let x be the number of pounds of coffee worth $9. Having said that, the number of pounds of coffee worth $3 is 120 - x. The equation relating the items before and after mixing is,
(x)($9) + (120 - x)($3) = (120)($5)
The value of x is 40. Therefore, the amount of coffee worth $9 and $3 to be used are 40 and 80 pounds, respectively.
Hello! One number is negative and the other one is positive. In this case, we should find the difference they are from 0 and add the numbers up. -11 is 11 units away from 0. 17 is 17 units away from 0. 11 + 17 = 28. The difference in temperature is 28 degrees Celsius.
Answer:
The numbers are 23 and 7
Step-by-step explanation:
1. Set up the equations
Let x = the greater number
and y = the smaller number. Then
(1) x - y = 16
4y = 4 times the smaller number and
4y - 5 = 5 less than 4 times the smaller number. Then
(2) x = 4y - 5
You have a system of two equations:
2. Solve the equations
The larger number is 23; the smaller number is 7.
3. Check
OK.
