Ответ:
First one is d and second one is c
Step-by-step explanation:
(6x+7)(x-8)
(6x)(x) = 6x^2
(6x)(-8) = -48
(7)(x) = 7x
(7)(-8) = -56
Add all like terms together and you get choice d.
(w+3)(w-3)
(w)(w) = w^2
(w)(-3) = -3w
(3)(w) = 3w
(3)(-3) = -9
Add all like terms together and you get choice c
Ответ:
(6x+7)(x-8)=6x^2-41x-56
Step-by-step explanation:
(6x+7)(x-8)
Apply FOIL method: (a+b)(c+d)=ac+ad+bc+bd= a=6x, b=7 c=x, d=-8=6xx+6x(-8)+7x+7(-8)
Apply minus & plus rules: =6xx-6(8x+7x-7)8
simplify: 6xx-6(8x+7x-7)8=6x^2-41x-56
