Answer:

D

Step-by-step explanation:

a perfect square trinomial is

a^2x^2\pm2(ab)xy+b^2y^2

factorized is

(ax\pm by)^2

so as you can see option A and B can't be, because they have -49y^2 and it has to be plus

so the other options are C and D

in the trinomial a=4 and b=\pm 7

the roots of a^2 and b^2

\pm2abxy=\pm2(4)(7)xy\\\\=\pm56xy

so it's option d with b=-7

16x^2-56xy+49y^2

Answer:

Step-by-step explanation:

The heights of neither the rectangular prism nor the triangular prism are given, so we don't know the volume of either.

If h is the height of the rectangular prism, then its volume is

6×8×h = 48

if the height of the triangular prism is h/2, then its volume is

(1/2)×24×8×(h/2) = 48

So we know the volumes are the same -- but we don't know what that volume is.
