What is the product of 2x + y and 5x – y + 3?

Goryan [66]

Answer:

The product of terms 2x + y and 5x – y + 3 is: $10x^2 + 3xy +6x -y^2 +3y$

Step-by-step explanation:

We need to multiply the two terms

$(2x + y) ( 5x - y + 3)\\=2x (5x - y + 3) + y( 5x - y + 3)\\=10x^2 -2xy +6x +5xy -y^2 +3y\\checking\,\, for \,\, the \,\, like \,\, terms\,\, (\,\,having\,\, same\,\, variables\,\,)\\=10x^2 -2xy +5xy +6x -y^2+3y\\=10x^2 + 3xy +6x -y^2 +3y$

The product of terms 2x + y and 5x – y + 3 is: $10x^2 + 3xy +6x -y^2 +3y$

Find an equation of the plane that is parallel to the xz-plane and is located 11 units to the right of the xz-plane in standard

mina [271]

Answer:

y = 11

Step-by-step explanation:

Since our plane is parallel to the xz plane, the x and z are independent of each other, i.e. they could be anything. So xz plane has an equation of y = 0. So if this plane is located 11 units to the right of the xz plane then its equation must be y = 11.
