BE = 2
Step-by-step explanation:
2(BE) = AC
2(3x - 7) = 8x - 20
6x - 14 = 8x - 20
6 = 2x
x = 3
BE = 3(3) - 7 = 2
The method of least squares is a widely used method of fitting curve for a given data

<em>only the last figure (i.e figure e) is shaded </em>
The shaded region is a triangle
Area of a triangle
= ½ × b × h
= ½ × 14 × 5
= ½ × 70
= 35yd²
