96 times 68.43 would be 6569.28, or 6579 7/25
You would expand becausee it isn't equal to anything
(x+3)^3=(x+3)(x+3)(x+3)
we can use binomial theorem or pascal's triangle
anyway, pascal's triangle is more practicl for this one
so
for the 3rd power

a=x
b=3

=
J)x^2 +2x +yx+2y-5x-10
x^2-3x+yx-10
k)5y^2(1-2y)
l)a(x+y+z)
So, you have $12,678. However, you want to earn $42,000 for a new car. If you want to figure out how much money you need, you need to subtract the number of money you want to earn by the number of money that you already have:

You would need
$29,322 more in order to buy the car.
Parentheses first: -3+1 = -2
Multiply: -2*2=-4
Subtract: -4-5=-9
Final Answer: -9
