Answer:

$40x^{2} y^{4} -70x^{2} y^{2} +90xy^{3}$

Step-by-step explanation:

$10xy(4xy^{3} -7xy+9y^2)$

1. 10xy · 4xy^3 = $40x^2y^4$

2. 10xy · -7xy = $-70x^{2} y^{2}$

3. 10xy · 9y^2 = $90xy^3$

Final step: add up all of those values together to make an equation!

Answer: $40x^2y^4+$ $-70x^2y^2+$ $90xy^3$

Final Answer: $40x^2y^4-70x^2y^2+90xy^3$

Solve:

STatiana [176]

The solutions to the equation $3-k=\sqrt{3k+1}$ are k = 1 and 8

The given equation is:

$3-k=\sqrt{3k+1}$

Square both sides of the equation

$(3-k)^2=3k+1$

Expand the left side of the equation above

$(3-k)^2=3k+1\\\\(3-k)(3-k)=3k+1\\\\3^2-3k-3k+k^2=3k+1\\\\9-6k+k^2=3k+1$

Write the quadratic equation in standard form

$k^2-6k-3k+9-1=0\\\\k^2-9k+8=0\\\\$

Factor the quadratic equation

$(k-8)(k-1)=0$

Use the zero product property

k - 8 = 0

k = 8

k - 1 = 0

k = 1

The solutions to the equation $3-k=\sqrt{3k+1}$ are k = 1 and 8
