We distribute:
7(5x+8)+12(x+4) =
35x + 56 + 12x + 48 =
47x + 104
Hope this helps!
7(5x+8) + 12(x+4)
First , do 7 times 5x and 7 times 8
so you get:
35x + 56 + 12 (x+4)
now, do 12 times x and 12 times 4
35x + 56+ 12x + 48
combine like terms to get :
47x + 104 :]
(35x + 56) + (12x + 48) = 47x + 104
7(5x+8)+12(x+4)
multiply through to get:
35x + 56 + 12x + 48
combine like terms to get:
47x + 104
參考: bp
35x + 56 +12x + 48
47x + 104.
7(5x+8)+12(x+4) = (35x+56)+(12x+48)
combining similar terms, we get
7(5x+8)+12(x+4) = (35x+12x)+(56+48)
adding
7(5x+8)+12(x+4) = 47x + 104
7(5x + 8) + 12(x + 4)
= 7*5x + 7*8 + 12*x + 12*4
= 35x + 56 + 12x + 48
= 35x + 12x + 48 + 56
= 47x + 104
35x + 56 + 12x + 48
47x + 104
7(5x+8)+12(x+4)
= 35x+56+12x+48
= 47x+104
