The answer is A. x³ - x² - 17x + 12.
To multiply a binomial by a trinomial, we multiply each term in the first polynomial by each term in the second polynomial.
Multiplying the first term then the second term of the first polynomial by each term in the second polynomial, we now have
(x+4)(x² - 5x + 3) = x³ - 5x² + 3x + 4x² - 20x + 12
Combining like terms to simplify and get the product equal to:
(x+4)(x² - 5x + 3) = x³ - 5x² + 4x² + 3x - 20x + 12
= x³ - x² - 17x + 12
Answer:
2x+15
Step-by-step explanation:
because this is easy
From 2.56 to 3.18; 3.18-2.56=0.62 increased
so if 2.56 represented 100%
0.62 represents ? %
cross multiply
?%= 0.62·100/2.56=24.21875 which rounded to the nearest whole is 24%
Answer is B).
the number of faces, edges and vertices the shape below has is 4, 4 and 6 respectively.
<h3>How to determine the number</h3>
It is important to note that according to Euler’s formula for any convex polyhedron, the number of Faces (F) and vertices (V) added together is exactly two more than the number of edges (E).
It is mathematically written as;
Face + vertices = 2 + edges
F + V = 2 + E
From the figure given, we can see that it is a kite
Number of vertices = 4
Number of faces = 4
2 + edges = faces + vertices
2 + edges = 4 + 4
2 + edges = 8
Edges = 8 - 2
Edges = 6
Thus, the number of faces, edges and vertices the shape below has is 4, 4 and 6 respectively.

I’m not sure if this helps, but the area of a hexagon with a perimeter of 12 inches would be 10.39 inches squared
