Answer:

Step-by-step explanation:
This question is illustrated using the attachment and will be solved using cosine formula

<em>Let the strawberry side be s, the Green beans be b and the pumpkins be p.</em>

The cosine formula in this case is:

Where



The equation becomes



Collect Like Terms


Using quadratic formula:

Where







or 
or 
or 
But length can not be negative.
So:

The common difference if there is one is the constant difference that occurs between any term and the term before it.... in this case:
There is no common difference,
dx=18,20,16,18 the difference or velocity is not constant...
d2x=2, -4,2 the acceleration is not constant...
d3x=-6,6 the thrust is not constant
Now we might be tempted to say that:
d4x=12 and say that that is constant and we COULD make a quartic equation fit all the data points, but without further data points in the sequence there is no mathematical proof that the quartic equation would produce accurate data points outside of the range given...
And solving a system of five equations for five unknowns is tedious for such a problem...a^4+bx^3+cx^2+dx+e=y
Answer:
Step-by-step explanation:
When you have a number (17) and want to know some fraction (2/5) of that number, you should multiply the number by the fraction.
17 * (2/5)
= (17*2)/5
= 34/5
= 6.8
You can then round this number up --> about 7 cars.
