Answer:
![8x^{3}-34x^{2}+25x-3](https://tex.z-dn.net/?f=8x%5E%7B3%7D-34x%5E%7B2%7D%2B25x-3)
Step-by-step explanation:
In order to solve this problem, lets take the two terms in the binomial (4x and -3) and, for each one, multiply them by each term in the trinomial (2x^2, -7x, and 1):
![(4x-3)(2x^{2}-7x+1)](https://tex.z-dn.net/?f=%284x-3%29%282x%5E%7B2%7D-7x%2B1%29)
![(4x*2x^{2})+(4x*-7x)+(4x*1)+(-3*2x^{2})+(-3*-7x)+(-3*1)](https://tex.z-dn.net/?f=%284x%2A2x%5E%7B2%7D%29%2B%284x%2A-7x%29%2B%284x%2A1%29%2B%28-3%2A2x%5E%7B2%7D%29%2B%28-3%2A-7x%29%2B%28-3%2A1%29)
![8x^{3}+(-28x^{2})+4x+(-6x^{2})+21x+(-3)\\](https://tex.z-dn.net/?f=8x%5E%7B3%7D%2B%28-28x%5E%7B2%7D%29%2B4x%2B%28-6x%5E%7B2%7D%29%2B21x%2B%28-3%29%5C%5C)
![8x^{3}-28x^{2}+4x-6x^{2}+21x-3](https://tex.z-dn.net/?f=8x%5E%7B3%7D-28x%5E%7B2%7D%2B4x-6x%5E%7B2%7D%2B21x-3)
Let's combine like terms to get our final answer:
![8x^{3}-28x^{2}-6x^{2}+4x+21x-3](https://tex.z-dn.net/?f=8x%5E%7B3%7D-28x%5E%7B2%7D-6x%5E%7B2%7D%2B4x%2B21x-3)
![8x^{3}-34x^{2}+25x-3](https://tex.z-dn.net/?f=8x%5E%7B3%7D-34x%5E%7B2%7D%2B25x-3)
Answer:
The coordinates of the intersection of two lines on a graph represent the values of <u>x</u> and <u>y</u> when you solve the system of equation.
Step-by-step explanation:
Answer:
The average number of trials required to get the first success
Choices:
–8 – 3i
–8 + 3i
8 – 3i
<span>8 + 3i
The additive inverse of the complex number a + bi is -(a+bi) = -a - bi
In this case, a = -8 and b = 3i
a + bi = -8 + 3i
additive inverse is: -(-8+3i) = +8 - 3i
The additive inverse of the complex number -8 + 3i is 8 - 3i. The 3rd choice.

Answer:
147
Step-by-step explanation:
Since it says need to use 3 to represent pi
well show the formula.
The radius is 7 so we square it, and do the formula.
A=3r²
A=3*49
A=147
