Answer:
Step-by-step explanation:
Rules :
[tex](-) \times (-) = +\\\\(+) \times (+) = +\\\\(-) \times (+) = -[/tex]
[tex]a) \ \ -4(-4+3)+2^2 = -4(-1)+4 = (-4 \times -1) + 4 = 4 + 4 = 8\\\\b) \ \ - 3 - 3 - 3 - (-3) = ( -3 - 3) -3 - (-3) = -6 -3 - (-3)\\ \ \ \ \ \ \ = -9 --3 =-9+3 = -6\\\\c) \ \ -17 + 2 (-2)(-2) = -17 + 2(-2 \times -2) = -17 + 2 ( 4) = -17 + 8 = -9\\\\d) \ \ (2 + (-3)(5))(3 + 2(-6)) = (2 + (-3 \times 5))(3 + (2 \times -6)) \\ = (2 + (-15))(3 + (-12)) = (2 -15)(3 -12)\\ = (-13)(-9) = (-13) \times (-9) \\= 13 \times 9 = 117[/tex]
