The coordinates of E are (5.75, 0).

<h3>What is midpoint?</h3>

The midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints.

Given that, C is the midpoint of AB, D is the midpoint of CB and E is the midpoint of DB.

Formula for coordinates of midpoint,

(x, y) = [(x1+x2)/2, (y1+y2)/2]

Coordinates of C;

(x, y) = (-10+8)/2, (14-2)/2

(x, y) = (-1, 6)

Coordinates of D;

(x, y) = (-1+8)/2, (6-2)/2

(x, y) = (3.5, 2)

Coordinates of E;

(x, y) = (3.5+8)/2, (2-2)/2

(x, y) =  (5.75, 0)

Hence, The coordinates of E are (5.75, 0).

Natalka [10]
b=a+3\\&#10;c=a+6\\&#10;a^2+b^2=c^2\\\\&#10;a^2+(a+3)^2=(a+6)^2\\&#10;a^2+a^2+6a+9=a^2+12a+36\\&#10;a^2-6a-27=0\\&#10;a^2-9a+3a-27=0\\&#10;a(a-9)+3(a-9)=0\\&#10;(a+3)(a-9)=0\\&#10;a=-3 \vee a=9\\&#10;

The length can't be negative, so the answer is 9 cm.

FinnZ [79.3K]
2x^2 + 3xy - 4y^2 when x = 2 and y = -4
= 2(2)^2 + 3(2)(-4) - 4(-4)^2 = 2(4) + (-24) - 4(16) = 8 - 24 - 64 = -80
