Answer:

₹ 2640

Step-by-step explanation:

The selling price is 10% more than the wholesale price, so is ...

₹ 20,000 + 10% × 20,000 = ₹ 20,000 × 1.10 = ₹ 22,000

The tax is 12% of this value, so is ...

₹ 22,000 × 0.12 = ₹ 2,640 . . . GST on the purchase

After a 80% reduction, you purchase a new washing machine on sale for $56.

Daniel [21]

80% = $56
1% = $56/80 = $70
100% = $70 * 100 = $700
Original price = $700
Hope this helps.

What are the roots of the quadratic equation below?<br> x2 + 2x= -5

muminat

Answer:

No real root.

Complex roots:

$x = -1 \pm 2i$

Step-by-step explanation:

$x^2 + 2x = -5$

$x^2 + 2x + 5 = 0$

There are no two integers whose product is 5 and whose sum is 2, so this trinomial is not factorable. We can use the quadratic formula.

$x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}$

$x = \dfrac{-2 \pm \sqrt{2^2 - 4(1)(5)}}{2(1)}$

$x = \dfrac{-2 \pm \sqrt{4 - 20}}{2}$

$x = \dfrac{-2 \pm \sqrt{-16}}{2}$

Since we have a square root of a negative number, there are no real roots. If you have learned complex numbers, then we can continue.

$x = \dfrac{-2 \pm 4i}{2}$

$x = -1 \pm 2i$
