If (a^2 + b^2) (x^2 +y^2) = (ax + by )^2 then which relation is true?

NikAS [45]

Answer:

Step-by-step explanation:

Hello,

Let's develop both expressions and try to re factorise.

$\forall (a,b,x,y) \in \mathbb{R}^4 \\ \\ (a^2+b^2)(x^2+y^2)=(ax+by)^2\\ \\(ax)^2+(ay)^2+(bx)^2+(by)^2=(ax)^2+(by)^2+2(ax)(by)\\ \\ (ay)^2+(bx)^2-2(ay)(bx)=0\\ \\ (ay-bx)^2=0\\ \\ ay-bx=0\\ \\ \boxed{\sf \bf ay=bx}$

Thanks

Katarina [22]

Answer:

7.5 jars

Step-by-step explanation:

There are 25 students in the art class.

Mr Jones is planning that for the project, each of the 25 students will need 0.3 jar of paint.

The amount of paint Mr Jones needs for this project is therefore the product of the number of students in the class by the amount of paint each student needs.

That is:

25 * 0.3 = 7.5 jars of paint

Mr Jones needs 7.5 jars of paint for the art project.
