Question

The formula for the area of a trapezoid with altitude k and bases m and n is . A=k/2 (m+n) solve for m.
I REALLYY need help!!!

Answer 1

A=k/2 (m+n)

2A/k = m + n

2A/k - n = m

m = 2A/k - n

Answer 2

A) (2A-k) /k

B) (2A+kn) / k

C) (2A-n) / k

Answer 3

\[\Large A = \frac{k}{2}(m+n)\]

\[\Large 2A = k(m+n)\]

\[\Large 2A = km+kn\]

\[\Large 2A-kn = km\]

\[\Large km = 2A-kn\]

\[\Large m = \frac{2A-kn}{k}\]

Answer 4

your a life saveerrr!!
