The area of a trapezoid is given by the formula A=h/2(a+b) .

Solve the formula for b.

Answers

Answer 1

Answer:

Answer:

(2A)/h -a =b

Step-by-step explanation:

A= [h(a+b)]/2 I rewrote the formula, because h and a+b are in the numerator.

2A=h(a+b) Multiply both sides of equation by 2

(2A)/h= a+b Divide both side by h

(2A)/h -a= b Subtract a from both sides

Arithmetic Sequence:

d=4

Step-by-step explanation:

This is an arithmetic sequence since there is a common difference between each term. In this case, adding 4 o the previous term in the sequence gives the next term. In other words, aₙ=a₁+d(n-1)
