30 - 4(2+5) = 2 This makes: 30 - 4(7) = 2 30 - 28 = 2
2xy - 4x plus 8y - 16 equals x plus 4 in parentheses multiplied by 2y minus 4 in parentheses. So, the factors are ( x + 4) and ( 2y - 4) .
22 = 4
(24/2)*8-3*(6-2)+1 = (12*8)-(3*4)+1 = 85
-20 Yes, that's correct. This is what it means:- 2(-3-5)-(2 + 2) And that is 2 x (-3-5) - (2 +2) = 2 x (-8) -(4) = -16 - 4 = -20
