Solve for x: tan(180-ø).tan(90+ø)+xcos(90+ø).(co s90-ø) =sinø.(sin180-ø) ​

What are “like terms”? why can we only add like terms?

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

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.
