2.5 cm2, point, 5, start text, space, c, m, end text and a base of
1.6
cm
1.6 cm1, point, 6, start text, space, c, m, end text. The height and base of triangle B are proportional to the height and base of triangle A.

step-by-step explanation:

b and c

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7
