Descending order for a polynomial means from highest value of exponent to the lowest value of exponent.
If you observe the options you can see that polynomial shown in option A is only listed in descending order i.e. starting from a maximum exponent of x and then moving towards lower exponents of x.
So answer to this question is option A
Answer:
answer is 26.6%
Step-by-step explanation:
i first converted the fraction "40/150" to a decimal by dividing 40 by 150
40 divided by 150 is .26 (rounded)
and then i did .26 times 100
which gave me 26.6
:P hope this helped even doe im kinda late-

One mile<span> is a greater measurement because it is equal to 1.6 </span>kilometers. Lets put one mile and one km into km.One <span>km is one km while one <span>mile is 1.6 <span>km.So that can also be seen as miles being a greater measurement.</span></span></span>
Answer:
- D. 2x² + 10xy + 8x² because (2x+ 2y) by (x + 4y)
Step-by-step explanation:
Let's mark the sides of the big square as x and a small square as y
<em>See attached picture below</em>
<u>Then we will have the sides of the rectangle:</u>
- x + x + y + y = 2x + 2y
- and
- x + y + y + y + y = x + 4y
<u>The area of the figure is:</u>
- A = lw
- A = (2x+ 2y)(x + 4y)
- = 2x² + 8xy + 2xy + 8y²
- = 2x² + 10xy + 8x²
Correct option is D.
