Math Counts Question 21

Algebra Level 1

a = 1 2 ( b 1 + b 2 ) h a = \dfrac12 (b_1 + b_2) h

Express h h in terms of a , b 1 , b 2 a,b_1, b_2 .

2a/(b1+b2) 2a/(b1+b4) 2a/(b1+b3) 2a/(b1+b5)

a = 1 2 ( b 1 + b 2 ) h a=\frac12(b_1+b_2)h

2 a = ( b 1 + b 2 ) h 2a=(b_1+b_2)h

2 a b 1 + b 2 = h \dfrac{2a}{b_1+b_2}=h

Actually, what is b 3 , b 4 , b 5 b_3,b_4,b_5 ? The answer is obviously the last one.
