bearhunter [10]

Answer:

$x^{2} +11x-10$

Step-by-step explanation:

$(13x^{2} +9x-4)-(12x^{2} -2x+6)$

Remove the brackets and multiply the minus sign through all the numbers in the second polynomial

$13x^{2} +9x-4-12x^{2} +2x-6$

Rearrange in the highest order

$13x^{2} -12x^{2} +9x+2x-4-6$

Simplify

$x^{2} +11x-10$

Answer:

acceleration of the golf ball will be faster. ( A )

Step-by-step explanation:

if you DROP a bowling ball vs a golf ball, the bowling ball will drop faster cause it’s heavier. but if you push a golf ball vs a bowling ball with the same force, the golf ball will be faster because it’s lighter. pushing a bowling ball with a lot of force will move it a certain amount, but moving a golf ball with that same force will go way past the bowling ball just cause it’s lighter.
