OpenStudy (calculusxy):

Find out the value of the expression that they gave you and then find another expression in the choices that has the same value.

OpenStudy (princeevee):

but i cant get it well : /

OpenStudy (calculusxy):

42 - (5 x 2) = ?

OpenStudy (princeevee):

c?

OpenStudy (calculusxy):

This questions looks a bit weird :\ 42 - (5 x 2) = 42 - 10 = 32 A. (5+3) x 2 = 15 x 2 = 30 B. 2(6+1) = 2(7) = 14 C. 5 x 8 - 2 = 40 - 2 = 38 D. 4 x 9 + 2 = 36 + 2 = 38

OpenStudy (e.mccormick):

So 24 - 5x^2 = ? cause the x2 looks like it is supposed to be x^2.
