What is the height of a triangle
with a base of 6 cm and area
of 18 cm2?

= 6cm

Area of Traingle = 1/2 x base x height

Which means that:

18 = 1/2 x 6 x height

x 2 on both sides

36 = 6 x height

divide 6 on both sides

height = 6 cm

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

4y - 6 + y^2 - 9 = y^2 + 4y - 15
