Which expression is equivalent to (x^2-5x)(3x^2+2x-9)

x (x - 5) (3 x^2 + 2 x - 9)

3 x^4 - 13 x^3 - 19 x^2 + 45 x

x (x (x (3 x - 13) - 19) + 45)

hope this helps!

the line of

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
