What is the volume of this rectangular prism?

Which table represents a linear function? i'll give brainliest to first answer ^'^

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)

If x is 6, then 7x= a. 13 b. 42 c. 42x d. 76
