Math question
 

can someone tell me if I figured this out correctly?

using the above formula, what is the value of M if h1=21,h2=14 AND d=49?

this is how I figured it....I hope the way Im typing it makes sense

m=9(21 + 14)/5 - (21-14)2 (squared)/49 +4 x 49
m=9(35)/5 - (7)2/49 + 196
m=315/5 - 49/49 + 196
m= 63-1+196 (simplfying the fractions so you have no demoniator)
m=258

You carry out the order of operations like a pro!

It's correct.

would you believe I havent done algebra in 24 years lol

thanks!!!
