Reduce the equation of straight line 2x+3y = 12 in double intercept form and hence mention its X-intercept and Y-intercept.

Given: x + y = 6. if xe (-15, -6, -1), then which of the following sets of ordered pairs are solutions? © {(-15, -21), (-6, -12), (-1, -7)} [(-15, 21), (-6, , 7)} {(-15, 21), (-6, 12), (-1, -7)}

Factor completely. 4p^2 + 36p + 81 express the answer in the form (ap + b)^2
