Answer:

$(x^n + 2)(x^n + 8)$

Step-by-step explanation:

The polynomial $x^{2n}+10x^n + 16$ can be factored exactly the same as the polynomial $x^2 + 10x + 16$ . Here it factors into two numbers which multiply to 16 but add to 8. These factors are 8 and 2. So it factors into the expression (x+8)(x+2).

For the polynomial $x^{2n}+10x^n + 16$ it factors into the same factors except x ^n is used instead. The factors are $(x^n + 2)(x^n + 8)$

Tems11 [23]

Answer:

He should pack 9 loaves of bread for a 12 day hiking trip if he eats the same amount of bread each day.

Step-by-step explanation:

Hint- This can be solved by Unitary method.

Sam used 6 loaves of elf bread on an 8 day hiking trip.

or in an 8 days trip he used 6 loaves of bread,

so in 1 day he would use $\dfrac{6}{8}$ loaves of bread,

so in a trip of 12 days he would use $\dfrac{6}{8}\times 12=9$ loaves of bread.

Therefore, he should pack 9 loaves of bread for a 12 day hiking trip if he eats the same amount of bread each day.

Answer:

60ft

Step-by-step explanation:

Let's x, y be the width and length of the surrounding rectangle. Since the area is 450 sq feet, this means xy = 450 or y = 450/x

The perimeter of this rectangle is (since there are 3 sides only)

f(x,y) = 2x + y

This is something we need to minimize. We can start by substituting y = 450/x

f(x) = 2x + 450/x

Let's take the first derivative of this function and set it to 0

$f'(x) = 2 - \frac{450}{x^2} = 0$

$2 = \frac{450}{x^2}$

$x^2 = 450 / 2 = 225$

$x = \sqrt{225} = 15ft$

y = 450 / 15 = 30ft

so the minimum perimeter that needs taping over is

f(x,y) = 2x + y = 2*15 + 30 = 60ft

The blanks in the given passage are filled with the appropriate words as follows-

Ecology is the study of how (1) plants, animals, and people live (2) together and help each other. But man sometimes forgets he (3) is a part of the (4) family of all living things. Here is an example. A planter is (5) talking about killing (6) weeds on his land. He remembers his first (7) experience with a weedicide. He was a (8) planter then, working (9) on a rubber plantation. He had a problem with weeds. The cost of weeding of the (10) fields by hand was getting (11) too high. So he used a new, cheap, and effective (12) method, good old Sodium Arsenate. He sprayed plenty of this (13) around to kill the weeds. The first thing to (14) react were the frogs.
