Core 1 maths help please very urgentWatch
has equation 4y + 3 = 2x
The point A (p, 4) lies on L1
(a) Find the value of the constant p.
The line L2
passes through the point C (2, 4) and is perpendicular to L1
(b) Find an equation for L2
giving your answer in the form ax + by + c = 0,
where a, b and c are integers.
The line L1
and the line L2
intersect at the point D.
(c) Find the coordinates of the point D.
(d) Show that the length of CD is 3
A point B lies on L1
and the length of AB = 80)
The point E lies on L2
such that the length of the line CDE = 3 times the length of CD.
(e) Find the area of the quadrilateral ACBE.
I cant do part e please explain someone
