please help me answer each question and write out each step. thank you.

Consider the area bounded by x = y? -3 and x = 2y. Find the area f the enclosed region. 7. Find the volume of the solid formed by rotating the region, R, bounded by the x-axis from above and the curve y = x2 -1 from below about the x-axis. 8. A particle moves along the x-axis with a velocity given by v(t) =13 -312 + 2t. The particle travels a certain distance from t = 0 to t= 3. a. When does the particle move left? Right? When does the particle stop? b. What is the net distance of that the particle travels from t = 0 to t= 3? c. What is the total distance that the particle travels from t = 0 to t= 3? Set up integral, do not evaluate. a Credit: Solve and show your work. (+3 points) 4 da = x' + 4x + 8
