i need on the following
convert the product into a polynomial:

c.(–2ax^2+3ax–a^2)(–a^2x^2)

d. (6.3x^3y–3y^2–0.7x)·10x^2y^2

note: the symbols such as ^ means exponents for the number to the right of it

c.

d.

Step-by-step explanation:

For this exercise you need to remember the following:

 1. The multiplication of signs:

2. The Product of powers property, which states that:

3. The Distributive property:

Knowing that, you can solve the multiplication of the polynomials:

c.

d.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

a) 0

step-by-step explanation:

i^413 x i^0 = 0 as any number multiplied by a zero is
