Question

Find the value of the expression x+y/4-9/2z when x=2, y=4 and z= -3
please answer quick​

Answer 1

Step-by-step explanation:

(x+y)

2

=z

2

−y

2

m(x+y)=n(z+y)

n(x+y)=n(z−y)

By cross multiplication

−m

2

+2mn+n

2

x

=

m

2

−n

2

y

=

m

2

+n

2

z

Hence, x=−m

2

+2mn+n

2

,y=m

2

−n

2

and the hypotenuse is m

2

+n

2

.
