28 is the LCM of 4 and 7 as 4*7 = 28
Answer:
see below
Step-by-step explanation:
-2x^4-x^3+8x^2-12
First list by highest power to lowest power
The highest power is x^4 so this is a 4th degree polynomial or a quartic polynomial
If you really mean the multiply sign
-2x^4-x^3*8x^2-12
-2x^4 - 8x^5 -12
-8x^5 -2x^4 -12
This would be a 5th degree or quintic
Answer:
196 is think
Step-by-step explanation:
because 224 - 28 = 196 then x = 196
If I'm interpreting this question correctly, then you want to know the tax per dollar. In order to find that, you need to find the percentage of $420 that equals $60. So,
420x = 60
x = 60/420
x = 0.1429 (rounded)
So, the tax rate would be this value multiplied by 100%.
0.1429 x 100% = 14.29%
