tangare [24]

Let H be hamburger and C be chesseburger.

H+C=559

2H=500

H=500/2
H=250

scZoUnD [109]

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

$5d^2+4d-3-(2d^2-3d+4)$

Collect the like terms together.

$5d^2+4d-3-(2d^2-3d+4)\\\\=5d^2+4d-3-2d^2+3d-4\\\\=5d^2-2d^2+4d+3d-3-4\\\\=3d^2+7d-7$

Hence, First option is correct.
