Answer:
A. The kinetic energy is quartered.
Step-by-step explanation:
The kinetic energy is quartered.
<span>distributive property to rewrite 3(7+x) = 21 + 3x</span>
<span>f(x)=3x+8 and g(x)=6x+6
(f + g)(x) = f(x) + g(x)
= </span>3x+8 + (6x + 6) = 3x + 6x + 8 + 6 = 9x + 14<span>
</span>(f + g)(x) = <span> 9x + 14
</span>
(f + g)(-1) = <span> 9*-1 + 14 = -9 + 14 = 5
</span>
<span>(f + g)(-1) = 5</span>
<span>.07375*34=2.5075 so the sales tax will
be about $2.50(if it needs to be rounded then it will be $2.51 and the
total cost will be $36.51 for the rounded sales tax)*</span>
