Slope intercept form :
y= -4/3x -2
Area of a rectangle = length * width.
So L * w = 864
But w = 2/3L
So we have L * 2/3L = 864
L^2 = 864 * 3/2 = 1296
L = âš 1296
L= 36 and width = 2/3 * 36 = 72/3 = 24

Hello,
We can set up two equations and solve the problem.
Let x be Crocus and y be daffodil. So:
x+y=40
.45x+.65y=20.40
Multiply the first equation by -.45 so to eliminate x. So we get:
-.45x-.45y=-18 Now add this to the second equation:
+.45x+.65y=20.40
And we get:
.20y=2.40 Divide each side by .25 to get:
y=12 Now we can find x by plugging 12 for y in the first equation:
x+12=40 Subtract 12 from both sides to get:
x=28
So now we know there are 12 daffodil and 28 crocus.
