Subtract the known trinomial from the total sum:
6x2 - 5x + 4 - 4x2 + 3x - 2 = 2X^2 -8x +6
Answer:
20
Step-by-step explanation:
80% of 25 is 20, even if you put it into a calculator
Yes because when you turn into a decimal it's 7.2
Ok because it only wants 3 significant digits your just take 103 and times it by the decimal form of 1.67% which is .0167 to get 1.720, now add that to 103 and multiply by .0167 again to get the populations after the second year(Use the population at that year to multiply by .0167). Do the same for the 3rd, 4th and 5th years and you should end with 112 million people.
The given equation, x9 - 5x3 + 6 = 0, is not a quadratic equation because the exponent of the first term is 9 while that of the second term is 3. The square of 3. If we are to square x3, we should only be getting x6 instead of x9. Therefore, the answer is NO.
