Algebra Problems! I need help?

We Answered:

Hi,

perimeter of the hexagon : 6x ==> Answer 2

perimeter of the octagon : 8(x/2) = 4x ==> Answer 3

They first say that 6x = 4x + 20
2x = 20
x = 10 ==> Answer 4

Now the first question is not clear : If you double the side of the hexagon, yoy double the side of the octagon. But if you must keep a difference of 20 inches between the perimeters, It's something else

In that case, 6(2x) = 8y + 20
8y = 12x - 20
2y = 3x - 5
y = (3x-5)/2 side of the octagon. ==> Answer 1

Hope it helps

Bye !!!

-4n²m³ (n²m+7) + 3nm(n³m²-6)
= -4n^4m^4 - 28n²m³ + 3n^4m³ - 18nm --> that's your final answer if all you wanna do is simplify it =/

you basically must multiply the numbers in front of the letters (i dunno what they're called), and add the exponents if they have the same base
