simplify:(-7)(-3)+(-2)^2+(-16)(2)
14x(-3y)-(-3)(-5y)
4[3x+(-2x)]-5(3x+2x)
(70a-40b)/(-10)
-3(x-5)-(x+7)
1)(-7)(-3)+(-2)^2+(-16)(2)
= +21+4-32
= +25-32
= -7
2)14x(-3y)-(-3)(-5y)
= -42xy-15y
3)4[3x+(-2x)]-5(3x+2x)
= 4[3x-2x]-5(5x)
=4(x)-25x
=4x-25x
= - 21x
4)(70a-40b)/(-10)
= 10(7a-4b)/(-10)
= -(7a-4b)
5)-3(x-5)-(x+7)
= -3x+15-x-7
= -4x+8
