16x² - 8x + 1 = (4x)² - 2 · 4x · 1 + 1² =(4x - 1)²
Used: (a - b)² = a² -2ab + b²
Answer:
The correct answer would be 2
<span>n >= 1125
First, make an equation to express the money raised after expenses.
55n - 15n + 10000 = m
The above expression can be read as "55 dollars per running is raised, but 15 dollars is spent per running to support them. Plus we get 10000 as a constant regardless of how many runner we have." Now convert that to an inequality for at least 55000 to be raised.
55n - 15n + 10000 >= 55000
Now solve for n
55n - 15n + 10000 >= 55000
40n + 10000 >= 55000
40n >= 45000
n >= 1125
So there needs to be at least 1125 runners in order to meet the goal of $55,000.</span>

Answer: 104 pages
Step-by-step explanation:
On 1/4 is actually 2/8 so on Monday and Wednesday together she read 3/8 + 2/8 = 5/8 of the 352 pages and 5/8 x 352 = 220.
Tuesday she read 28 pages so she has read 220 + 28 = 248 pages.
She must read 352 -248 = 104 pages more
