The equation a = startfraction one-half endfraction left-parenthesis b 1 plus b 1 right-parenthesis.(b1 + b2)h can be used to determine the area, a, of a trapezoid with height, h, and base lengths, b1 and b2. which are equivalent equations? check all that apply.

2a/h -b2=b1

a/2h-b2=b1

2a-b2/h=b1

2a/b1+b2=h

a/2(b1 +b2)=h

The equivalent expressions are:

Step-by-step explanation:

Given equation for finding area of a trapezoid:

where represents area, represents height and represents the base lengths of the trapezoid.

Evaluating by rearranging the equation to find an equivalent equation.

Multiplying both sides by 2.

Dividing both sides by

Evaluating by rearranging the equation to find an equivalent equation.

Multiplying both sides by 2.

Dividing both sides by

Subtracting both sides by

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
