Using <span>Descartes' rule of signs.
There are 4 changes of signs of coefficients:
+ to - (+x^6-x^5)
- to + (-x^4+4x^3)
+ to - (+4x^3-12x^2)
- to + (-12x^2+12)
Therefore, there are 4,2 or 0 positive roots </span><span><span>at most</span>. So it must be the third answer.

Answer:
There are 23 dimes in the box
Step-by-step explanation:
Let nickels=n
Let dimes=(35-n)
Equation: 0.05n+0.10(35-n)=2.90
Multiply both sides by 100: 5n+10(35-n)=290
-5n+350=290
-5n=-60
n=12
35-12=23
Therefore, there are 23 dimes in the box
The most likely and preferred unit of measurement for the number of strawberries is pounds.
Given that,
Jamison owns a smoothie shop. He is placing an order for strawberries and pineapple juice for a new specialty drink. Which would be the most appropriate unit of measurement for the number of strawberries Jamison will order is to be determined.
<h3>What is a measurement unit?</h3>

Here,
Strawberries have moderate weight and are solid as well so the most preferred unit for the measurement is ounces for moderate use and pound for commercial use,
Since Jamison has a shop, and he uses strawberries for commercial use to make drinks and sell it further, implies pounds is the appropriate unit of measurement.
Thus, The most likely and preferred unit of measurement for the number of strawberries is pounds.

Sounds like your describing complementary angles (a pair of angles that add up to be 90 degrees) but not super sure based on that description you have there.
Tell me does it look like this:
2,3,7,8=
1)3*7=21
2)2*8+7=32
3)7*3+8=29
4)7*3+2=23
5)7*8 divided by 2=28
6)8*3=24
7)2*3*8=48
Hopes This Helps :)
