Question

Solve for b2 in A = h(b1+b2), if A = 16, h = 4, and b1 = 3.

Answer 1

1

Answer 2

in the formula,

divide both sides by h;
then subtract b1 from both sides...

this solves for b2...

now just plug in those givens to get a value for b2....:)

Answer 3

16=4(3+b2)
16=12+4b2
16-12=4b2
4=4b2
4/4=b2
b2=1

Answer 4

plug b2=1 into the equation to test.
