Which system will have an infinite number of solutions?
a.
–4y = –6x + 8
y=3/2x-2

b.
–4x + 5y = 8
5y = –4x + 6

c.
–2x + 4y = 3
y=1/2x+6

d.
2x – 6y = 9
5y = –4x + 6

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
