The simplification of the polynomial expression will give 3x² - 20x + 8.
<h3>How to illustrate the polynomial?</h3>
The polynomial expression is given as:
(5x² + 13x4) (17x² + 7x - 19) + (5x-7)(3x + 1)
= 5x² + 13x - 4 - 17x² - 7x + 19 + 15x² + 5x - 21x - 7
Then collect like terms
= 5x² + 15x² - 17x² + (13x - 7x + 5x - 21x) - 4 - 7 + 19
= 3x² - 20x + 8.

Answer:
5/6 (please give branliest)
Step-by-step explanation:
5/6 * 1/3 = 5/18
5/18 / 2/3 = 5/12
5/12 / 1/2 = 5/6
Answer:
Sedimentary rocks usually form in visible layers
Step-by-step explanation:
A is wrong because not all igneous rock is formed by pressure
B is wrong because sedimentary rock is usually a surface rock
C is wrong because the rock cycle is sporadic and doesn't always end in igneous rock
D is correct because sedimentary rock is formed from years and years of sediment layering on top of each other
Answer :-
Area of the rectangular painting = 6348 cm²
length = 92 cm
Area = length × width
6348 cm² = 92cm × width
=> 6348cm² / 92cm = width
=> width = 69 cm
Thus, the width of the rectangular painting is 69 cm
The expression for the price Samantha paid for the candies is mc/n dollars.
We know that an expression, often known as a mathematical expression, is a finite collection of symbols that are well-formed in accordance with context-dependent principles.
Given that the number of candy that Samantha bought is m.
There are n candies in 1 pound.
i.e. 1 candy in 1/n pounds.
Then m candies in m/n pounds.
Also given that each pound costs c dollars.
So, m/n pound costs (m/n)*c dollars i.e. mc/n dollars.
We can conclude that the expression for the price Samantha paid for the candies is mc/n dollars.
