27 adult elephants would weigh 445500 pounds or 222.75 tons
3k+10=2k-21
move 2k to the other side
sign changes from +2k to -2k
3k-2k+10=2k-2k-21( combine like terms)
3k-2k+10= -21
k+10=-21
move +10 to the other side
k+10-10= -21-10
k= -21-10
answer:
k= -31
The expanded form of the equation is x^4-24x^3+222x^2-240+960
<h3>Expansion of expression</h3>
Given the expression below;
(x-3)(x-5)(x-7)(x-9)+15
Expand
(x-3)(x-5)(x-7)(x-9) + 15
(x^2-5x-3x+15)(x^2-9x-7x+63) +15
(x^2-8x+15)(x^2-16x+63) + 15
Expand further to have;
x^4-16x^3+63x^2-8x^3+144x^2-504+15x^2-240x+945+15
x^4-24x^3+222x^2-240+960
Hence the expanded form of the equation is x^4-24x^3+222x^2-240+960
