Answer:

Step-by-step explanation:

If the question is to factorize

$x^4-17x^2+16\\\\x^4-x^2-16x^2+16\\\\=x^2(x^2-1)-16(x^2-1)\\\\=(x^2-1)(x^2-16)\\\\=(x+1)(x-1)(x-4)(x+4)\\$

nadia wants to enclose a square garden with fencing has an area of 141 ft.² to the nearest foot how much fencing will she need e

Andreas93 [3]

We know that area of the square is 141 square feet. Therefore, we can figure out the dimension of square using formula for area as shown below:

$Area=a^{2}\\141=a^{2}\\a=\sqrt{141}=11.874$

We know that fencing is used along the sides of the square. Therefore, amount of fencing required will be equal to perimeter of square.

Hence, we can write:

$\text{Amount of fencing}=\text{Perimeter of square}$

$\text{Amount of fencing}=4a=4(11.874)=47.496$

Upon rounding to nearest foot, we get the amount of fencing required as 48 feet.

The fastest runs 2,464 feet in 22.4 seconds. How many miles per hour is that?

Juliette [100K]

Thirty miles per hour. First you divide 2,464 feet by 22.4. you should get 110 feet which is per second, then you multiply it by 60 representing one minute but in seconds, you should get 6,600 feet per minute, then you multiply it by 60 mins and you should get 396,000 feet per minute. Next, you multiply 396,000 by 24 hours, the result is 9,504,000 feet per hour. Finally, you divide 9,504,000 by 5280 (there is 5280 feet in one mile) and the answer is 30 miles per hour.
