Answer:

(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

Answer:

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

I NEED HELP PLEASE !!!
laila [671]

Answer:

D. 1/44

Step-by-step explanation:

divide both sides by the # in front of X - in this case its 6. you should get x= 3/22 ÷ 6 and get your answer there by plugging in the calculator. or on paper-

do 3/22 × 1/6 which is also reduced to --> 1/22 × 1/2 and that is 1/44 but you should be able to jist plug 3/22÷ 6 in if you take middle/highschool math anyways
