distribute 2 to 10 and 1 so is it (10 + 1) squared or multiplied by two?
OpenStudy (jadeishere):
if it's (10 + 1) ^2 - 52 then it'd be (10 + 1)(10 + 1) - 52 100 + 2 - 52
OpenStudy (anonymous):
it is (10+1)^2 - 5 ^2
OpenStudy (jadeishere):
Ohhhh, makes more sense!! (10 + 1)^2 - 5^2 then do PEMDAS 11^2 = 121 5^2 = 25 121 - 25 = 96
