Dawn says 22(23)(4) is equal to 6(4). Javier says 22(23)(4) is equal to 22(212). Who is right? Explain. I NEED HELP ASAP PLZ

Find the volume of the described solid. the solid lies between planes perpendicular to the x-axis at x = 0 and x=7. the cross sectionsperpendicular to the x-axis between these planes are squares whose bases run from the parabolay=-31x to the parabola y = 30/x. a) 441b) 147c) 864d) 882

Evaluate the expression. (9 + 5)(3 + 2)0

Put the equation in slope intercept form by solving for y
