What is 147 divided by 3​

Ineed to know the answer to this algebra question.

The square root of 9x plus 7 plus the square rot of 2x equall to 7

Ialready asked this but i never got an answer. will give a high rating and perhaps brainliest. choose the linear inequality that describes the graph. the gray area represents the shaded region. y ≤ –4x – 2 y > –4x – 2 y ≥ –4x – 2 y < 4x – 2
