25 POINTS Lines a,b,c, and d are in the same plane. Line a is parallel to line c. Lines d and c are perpendicular to line d. Bas

polet [3.4K]

Assuming that the actual question reads lines b and c are perpendicular to line d

we are given that c is perpendicular to line d and parallel to line a. Since b is also perpendicular to line d, a b and c must all be parallel (draw it out will make a lot more sense)

So b is also parallel to line a

Perform the specified operations on the polynomials: Subtract 2x2−3xy+4y2from 3x2−5xy−6y2

tankabanditka [31]

Answer:

Solution to the given expression is $(x^2 -10y^2 -2xy)$

Step-by-step explanation:

Here, the given expression are:

$P(x) = 2x^2- 3xy+4y^2\\Q(x) = 3x^2 - 5xy-6y^2$

To Solve for : Q(x) - P(x)

Now substitute the value of P(x) and Q(x) , we get:

$Q(x) - P(x) = P(x) = (3x^2 - 5xy-6y^2) - (2x^2- 3xy+4y^2)\\= 3x^2 - 5xy-6y^2 - 2x^2+3xy-4y^2\\=x^2-10y^2-2xy\\\implies Q(x) - P(x) = (x^2-10y^2-2xy)$

Hence solution to the given expression is $(x^2 -10y^2 -2xy)$
