(y + 3z)(y^2 - 3yz + 9z^2)
12x^2+24x+12 12(x^2+2x+1) 12(x+1)^2
The GCF is 12.
(x + 3)(x + 4)
(x + 12)(x + 7)
8x + 9z
12x-4y+9z+2y =12x-2y+9z
(y + 3z)(y^2 - 3yz + 9z^2)
9z-5z = 30+z 3z = 30 z = 10
9z+8 = 3z-10 9z-3z = -10-8 6z = -18 z = -3
9z
3-5z
45
The following steps lead you to the correct answer: 9z = 5z + 16 9z - 5z = 16 4z = 16 z = 4, thus the correct answer is z = 4
-y+9z-16y-25z= -y-19y+9z-25z= -20y-16z There you go, are you happy. p.s it was easy (im 13yr)
It's 9z-7. because: you do the 8 times z first (8z) then add the z, (9z), then minus 7. 9z-7
It is 20z-18 when simplified
