Solve the equation: A=(b1 + b2)/2 • h for h

Given that the equation is

We need to solve the equation for h.

Value of h:

Let us solve the equation h.

Thus, multiplying both sides of the equation by 2, we get;

Simplifying the terms, we get;

Dividing both sides of the equation by the term , we get;

Thus, the value of h is

Therefore, the solution of the equation for the value h is

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
