The area of a trapezoid is 18 square meters. One base is 3 meters long and the other is 6 meters long. Find the height of the trapezoid. Step 2 of 3 : Without substitution, solve the formula chosen in the previous step for the unknown variable in terms of the known variable(s).

height = 4 meters

h = 2A / ( a +  b )

Step-by-step explanation:

Let A represent the area of the trapezoid, h, the height a, the length of one base and b, the length of the other base

Area of a trapezoid, A = ( a + b)* h / 2

Now let's slot in the given values

A= 18 sq meters

a = 3 meters

b = 6 meters

we have;

18 = ( 3 + 6 ) * h /2

18 = 9 * h /2

Cross multiply

18*2 = 9h

36 = 9h

divide both sides by the coefficient of h (9)

4 = h

therefore, h = 4 meters

To solve for h without substituting

From A = ( a + b )* h /2

cross multiply

2*A = ( a + b )* h

divide both sides by ( a + b )

2A / ( a + b ) = h

therefore,

h = 2A / ( a +  b )

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
