Write the product in its simplest form: 7x^6 y^3 • (-7y^2)

Please explain this to me when you answer it

Step-by-step explanation:

7x6y².y.(-7y²)

7y²[x6y-1]

-49x^6y^5

Step-by-step explanation:

multiply the like terms (7y^3 and -7y^2)

7*-7 = -49

y^3+2 = y^5

combine the terms

-49x^6y^5

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
