Assuming that Ralph budgeted $180 instead of $175 entertainment. He spent $35 per date and let "x" be the number of dates he attended. He spent $15 to go out with friends and let "y" the number of times that he go out with friends.
The correct expression is the "B" which is 35x + 15y =180.
The expression above is an example of a polynomial. See the explanation below for how it works.
<h3>What is a polynomial?</h3>
Polynomials are the sums of terms of the form k⋅xⁿ, where k is any number and n is a positive integer.
<h3>What is an example of how a polynomial works?</h3>
Let us use the following exercise.
Give an examples polynomials p(x),g(x),q(x) and r(x), which satisfy the division algorithm and (i) deg p(x)=deg q(x)
<h3>What is the solution to the above?</h3>
(i) deg p(x) = deg q(x)
Recall the formula
Dividend = Divisor x quotient + Remainder
p(x)=g(x)×q(x)+r(x)
When the divisor is constant, the degree of quotient equals the degree of dividend.
Let us assume the division of 4x² by 2.
Here, p(x)=4x²
g(x)=2
q(x)= 2x² and r(x)=0
Degree of p(x) and q(x) is the same i.e., 2.
Checking for division algorithm,
p(x)=g(x)×q(x)+r(x)
4x² =2(2x²2)
Hence, the division algorithm is satisfied.

S=15
Whatever the number of sides of a polygon,
the sum of its exterior angles is always <span>360∘</span>
Further, each pair of exterior angle and interior angle adds up to <span>180∘</span>
Hence in a polygon with s sides (or angles),
the sum of all the interior and exterior angles would be <span><span>180∘</span>×s</span>
and sum of interior angles would be <span><span>180∘</span>×n−<span>360∘</span>=<span>180∘</span><span>(s−2)</span></span>
As sum of angles is <span>2340∘</span>
Hence, <span>180<span>(s−2)</span>=2340</span> or <span>s−2=<span>2340180</span>=13</span>
and <span>s=13+2=15</span> and polygon is a Pentadecagon.
i hope u understand :)
Answer:
Son résultat est faux parce que son numéro est peut-être mal numéroté ou parce qu'il utilise une solution différente.
