Can someone find the area of the rhombus?

Solve the equation 3x2 + 19x + 9 = 0 to the nearest tenth.

What is the product? (x2+3y+7) [yy+1)

Identify the converse of the following conditional: if a point is in the first quadrant, then its coordinates are positive. if the coordinates of a point are not positive, then the point is not in the first quadrant. if the coordinates of a point are positive, then the point is in the first quadrant. if a point is in the first quadrant, then its coordinates are positive. if a point is not in the first quadrant, then the coordinates of the point are not positive.
