NOT TO SCALE Som
ACE is an isosceles triangle CW is perpendicular to AE. Angle CAH=70
and AH = 5 cm.
Calculate the length of AC correct to 5 significant figures
Show that it rounds to 14.2 cm.
[3]

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares
