Answer:
Point X is the center of dilation.
Step-by-step explanation:
Consider the below figure attached with this question.
It is given that trapezoid TRAP was dilated by a scale factor of 1/2 to create trapezoid T'R'A'P'.
We need to find the center of dilation.
All points of the figure are expanded or contracted about a fixed point, that point is know as center of a dilation.
To find the center of a dilation, draw 4 lines which are connecting vertices with their corresponding images. The intersection point on these lines is the center of a dilation.
From the 2nd figure it is clear that lines TT', RR', AA' and PP' intersect each other at point X.
Therefore, point X is the center of dilation.
PART A
s = <span>the number of packets of strawberry wafers ;
c = </span><span>the number of packets of chocolate wafers ;
3 </span>× s + 1 × <span>c = 30 ;
s + c = 22 ;
PART B
</span>The method of solving "by substitution"<span> works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.
</span>
c = 30 - 3s;
s + ( 30 - 3s ) = 22;
30 - 2s = 22;
30 - 22 = 2s;
8 = 2s;
s = 4 ;
c = 30 - 12 ;
c = 18 ;
I’m not the best at explaining, but I hope with the way I did the problem, helped

Answer: y = -2
Answer:
A prime polynomial is similar to a prime number: it cannot be factored. The binomial x^2 +1 cannot be factored using real numbers as coefficients.
