The area of a trapezoid is given by the formula A = (b 1 + b 2)h, where base b 1 is parallel to base b 2 and h is the height. Solve the formula for b 2. Show your work.
A = (b1 + b2)h b1 + b2 = A/h b2 = (A/h) - b1

Questions asked by the same visitor
The sum of two numbers is 48. If one third of one number is 5 greater than one sixth of another number, which of the following is the smaller number? 6 26 22 42
Question
Updated 1/26/2015 8:57:39 AM
Let the 2 numbers be x and y.

x + y = 48- >(1);
1/3x = 5 + 1/6y- >(2); Multiplying (2) by 6, we get: 2x = 30 + y; 2x - y = 30 - >(3);

(1) + (3), we get:

3x = 78; x = 26. y = 48 - 26 = 22.

The smaller number is 22.
