Answer:
x^2+10x+25 is a polynomial
Step-by-step explanation:
A polynomial is an expression with exponets such as x^2 therefore your eqation that will become x^2+10x+25 is always a polynomial
Assuming you meant (x+5)^2
Hello!!
25 - 20 = 5
5/20 = 0.25
0.25 * 100 = 25%
Good luck :)
I assume that the numbers are supposed to be written as 7.14 x 10^10 for December and 3.21 x 10^10. The total mail delivered is the sum of these two numbers.
(7.14 x 10^10) + (3.21 x 10^10) = 1.035 x 10^11
Answer:
-39+5(-41)=244
Step-by-step explanation:
Consider 3 consecutive integers: (smallest) x, x+1 and x+2 (largest)
Five times the smallest means 5x
Sum of the largest and five times the smallest means x+2+5x
This sum is -244 means x+2+5x=-244
Solve this equation
x+2+5x=-244
6x+2=-244
6x=-244-2
6x=-246
x=-41
So, smallest number is -41, second is -40 and largest is -39
= -39+5(-41)=244
Hope this helps, have a nice day/night! :D
Answer:
$5.20
Step-by-step explanation:
Find the tax rate first:
$1.20
