Answer:
The area of the rectangle is 15y^6 -40y^5 + 10y^4
Step-by-step explanation:
In this question, given the width and length of a rectangle in polynomial form, we are asked to express the area of the rectangle in terms of the polynomials.
Generally, the area of a rectangle A is mathematically equal to Length * width
Using the terms in the question, our area A = 5y^3 [3y^3 -8y^2 +2y]
Opening this bracket we have;
15y^6 -40y^5 + 10y^4
300 = 5t + 150
150 = 5t
30 = t
1990+ 30 = 2020

have any notes for reference?
Step-by-step explanation:
Answer:
a 5-point star has rotational symmetry. A 5-point star is a two-dimensional polygon in the shape of a star with five points, or tips.
So symetry will have a total of 360 degrees, then if you divide it by 5 ( the number of point in the star) you will get 72 degrees each so it has 5 reflections
