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

The perimeter of a rectangular garden is

olganol [36]

Perimeter = 2 ( width + length)
294 = 2 (56 + length)
294/2 = 56 + length
147 = 56 + length
147 - 56 = length
91 = length

so the length is 91 feet
