N = ((n-1) + 4) + 4, to my understanding.
although your answers seem right written in the columns, but your method of applying numbers to equation seems incorrect in 'expand' column. for example, answer for 3 should be something like this...
3 21 17+4
4 25 21+4
hope it helps.

Step-by-step explanation:
Answer:
$184
Step-by-step explanation:
87 is 5 less than 1/2 of the price without a sale. in that case 92 would be half the cost. To find the full value you would multiply 92 by two to get 184
P = k/w^2
<span>first of all you need to find k </span>
<span>But I kind of don't like the units of each value so let say </span>
<span>400KPa = 4 * 10^5 Pa = 4 * 10^5 N/m^2 </span>
<span>2 cm = 2 * 10^-2 m </span>
<span>input values in the equation </span>
<span>4*10^5 = k/(4*10^-4) >>> k = 160 N </span>
<span>P = 160/w^2 </span>
<span>it said if she wears a heel with a width of .5 cm </span>
<span>P = 160(0.5 * 10^-2)^2 >>> P = 6400 KPa</span>
Answer:
a. Andrea is incorrect
b. By solving for x, we find that x does not equal 8, but it is equal to 7.
Step-by-step explanation:
8+4=2(x-1)
8+4=2x-2
12=2x-2
14=2x
x=7
