Answer:

+(x + y) {}^{2}  = 6 {}^{2} \\ x {}^{2} + 2xy + y {?}^{2}  = 36

x {}^{2}  + y {}^{2}  = 36 - 2xy

q = 3(x {}^{2}  + y {}^{2} )

q = 3(36 - 2xy) = 108 - 6xy

Triss [41]
<h2>Hello!</h2>

The answer is:

C.  0.25\frac{g}{cm^{3} }

<h2>Why?</h2>

The density is the relation between the mass and the volume of an object. We are given four options to chose, and we can find the correct one by doing the following calculations:

Density=\frac{mass}{volume}=\frac{5g}{20cm^{3}}=0.25\frac{g}{cm^{3}}

So, the correct options is C.  0.25\frac{g}{cm^{3} }
