Multiply (x2 + 2x + 3)(4x2 - 2x + 1).

4x^4 + 6x^3 + 9x^2 - 4x + 3

I simplified

hope this helped bud

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
