23.6 ft. Round your answer to the nearest tenth of a cubic foot.

V≈155.76ft³

Step-by-step explanation:

V≈155.76ft³ nearest 10th will be 160 ft3

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

not sure but it may be b, as i said i'm not sure.
