Hello
The answer is volume because since all matter must have texture and in order for something to have texture is to have volume, than matter has volume.
A^2 + 9 = 36 now solve subtract 9 from both sides to get a^2 = 27 then find the square root of 27 and that should be your answer so like 5.196 something
I believe its d because you subtract (-3 -7 1 9) from both sides
X/7=14
Then you multiply 14*7 and x=98
