A triangle has an area of 9 square inches. If the triangle is dilated by a scale of 1.5,
which expression can be used to determine
the area, in square inches, of the new
triangle?
A
1.5 x 9
B 2 x 1.5 x 9
C (1.5)2 x 9
D (1.5)3 x 9

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.

what’s the question?
