The formula for the area of a trapezoid is a=1/2h(b+b) express b in terms a,h,and b2
Lunna [17]

The area of a trapezoid is           
                                          A  =  (1/2) (h) (b1 + b2).

( 'h' is the height of the trapezoid.  'b1' and 'b2' are its two bases.)

You want the equation solved for one base.

                                                 A  =  (1/2) (h) (b1 + b2).

Multiply each side by  2 :                    2A  =  h(b1 + b2)

Divide each side by  'h' :                    2A/h = b1 + b2

Subtract  b1  from each side:    <em>2A/h - b1  =  b2</em>

-5(a + 3) = -55<br> What is the value of a?
Kobotan [32]

Answer:

a=8

Step-by-step explanation:

-5(a+3)=-55

First you times the bracket by -5

-5a-15=-55

Then you add the 15 to -55 because since the 15 is a negative on the right it has to be the opposite to the left

-5a=-40

Then you divide both sides by negative 5

-5a .     = .      -40  

---------         ----------

- 5                    -5

a= 8

Which expression is irrational?
Mrrafil [7]

Answer:

\sqrt{50}

Step-by-step explanation:

An irrational number is a number that isn't a whole number (integer).

\sqrt{50} = 7.07

\sqrt{1} = 1

\sqrt{25 = 5

\sqrt{9} = 3

The first one is the only one that isn't an integer. So it is the answer.
