Z^2 - 3z - 18 = (z+p)(z+q) What do you know about the signs of p and q?

Well if you have 20 bats you probably want 20 balls? you don’t have enough context to answer the question.

To find the x-intercept, make  y  equal to zero, and solve for  x. to find the y-intercept, make  x  equal to zero, and solve for  y.explanation: y=4x−2x-intercept0=4x−2add  2  to both sides of the equation.2=4xdivide both sides by  4.24=xsimplify.12=xswitch sides.x=12y-intercepty=4(0)−2y=−2

Not only are the four sides congruent but all angles need to be 90° otherwise it could be a parallelogram or something
