The formula for a trapezoid relates the area a, the two bases, a and b, and the height, h. a=1/2h(a+b) .solve for b

Step-by-step explanation:

Solving for a specific variable in a formula requires algebra. The formula for area of trapezoid is given as:

We can write this as:

We can multiply the "2" with A to get:

Now we use "distributive property" on the right side of the equation to get [note: distributive property is  a(b+c) = ab + ac ]:

Since we want to solve for b, we keep this term to one side and take others to another and use algebra to come up with an expression for b:

This is solving for b, or the expression for b.

no, x cannot be the same number. in all of them, x is 1. for one input there is another output. g is not a function

answer: 20

step-by-step explanation: subtract the minimum date value from the maximum data value to find the date range. in this casem the date range is 42 - 22 = 20

hope this ! : ) ~zane
