Answer:
thx chief
Step-by-step explanation:
1. 1,728
2. You can't tell because it doesn't say the amount one serving will serve, and how many servings she is serving, and how many people come to her party. Sorry!!
I hope I helped with the first one!
We have that
-7x-60=x²<span>+10x
</span>x²+10x+7x=-60
x²+17x=-60
(x²+17x+8.5²)=-60+8.5²
(x+8.5)²=12.25
(+/-)(x+8.5)=√12.25--------> (+/-)(x+8.5)=3.5
(+)(x+8.5)=3.5------> x=-5
(-)(x+8.5)=3.5------> x=-12
therefore
(x+5)*(x+12) is equivalent to -------> -7x-60=x²+10x
the answer is
(x+5)*(x+12)
So to find the medium you need to put the numbers in order from least to greatest so for the first one it would be like this 103, 111, 113, 114, 122, 129,
<span>130, 138, 140, 141, 145 and then you find the number that is in the middle of the set so for sample one it would be 129</span>
