Evaluate the expression for x = 4 and y = 5. 6(x^2 - y) - y^2

OpenStudy (anonymous):

so 6(x^2-y)-y^2 change it to 6(4^2-5)-5^2

OpenStudy (anonymous):

you have to first work from the parenteses

OpenStudy (anonymous):

so u would do PEMDAS more less

OpenStudy (anonymous):

its actually 41

OpenStudy (anonymous):

(4^2-5) (8-5) 3

OpenStudy (anonymous):

so now u have 6^3-5^2

OpenStudy (anonymous):

so you will do

OpenStudy (anonymous):

6^3 then 5^2 then subtract them. 18-10 giving you 8

OpenStudy (anonymous):

wrong because it 4 squared which is 16 minus 5 which is 11 than multiply it by 6 which is 66 then 5 squared is 25 then 66 - 25 is 41

OpenStudy (anonymous):

8 or 41? cause they both an option

OpenStudy (anonymous):
