Answer:
-4x^2+2y^2-x+9y-50=0
X = 5 Y = 2, 9
Step-by-step explanation:
C. x³-4x²-16x+24.
In order to solve this problem we have to use the product of the polynomials where each monomial of the first polynomial is multiplied by all the monomials that form the second polynomial. Afterwards, the similar monomials are added or subtracted.
Multiply the polynomials (x-6)(x²+2x-4)
Multiply eac monomial of the first polynomial by all the monimials of the second polynomial:
(x)(x²)+x(2x)-(x)(4) - (6)(x²) - (6)(2x) - (6)(-4)
x³+2x²-4x -6x²-12x+24
Ordering the similar monomials:
x³+(2x²-6x²)+(-4x - 12x)+24
Getting as result:
x³-4x²-16x+24

Make sure the number is rational if it isn’t
Hey there!
For this problem, you'll first want to calculate how much the bill will be including the 20% tip. To convert a percentage to a decimal, take the decimal point to the left two numbers. Remember that 20 is the same thing as 20.0.
20% = 0.2
Next, multiply the amount by that decimal, then add the tip to the total bill.
<span>$52.35 * 0.2 = $10.47 (tip amount)
</span>$52.35 + $10.47 = $62.82 (total including tip)
Now, just divide that by four people to get your final answer.
$62.82 / 4 = $15.705
Because you can't have half of a cent, the problem probably just wants you to round up to $15.71, even though this will make the bill equal to $62.84.
Hope this helped you out! :-)
