Answer:
3x³ + 23x² + 63x + 55
Step-by-step explanation:
Given
(3x + 5)(x² + 6x + 11)
Each term in the second factor is multiplied by each term in the first factor, that is
3x(x² + 6x + 11) + 5(x² + 6x + 11) ← distribute both parenthesis
= 3x³ + 18x² + 33x + 5x² + 30x + 55 ← collect like terms
= 3x³ + 23x² + 63x + 55
If you would like to solve 7x - (25x^2 + 12x), you can do this using the following steps:
7x - (25x^2 + 12x<span>) = 7x - 25x^2 - 12x = - 25x^2 - 5x
</span>
The correct result would be <span>- 25x^2 - 5x.</span>
Answer:
y = 4/3x - 10
Step-by-step explanation:
Slope: 4/3
y-intercept: -2 - (4/3)(6) = -2 - 8 = -10
Answer:
A
Step-by-step explanation:
Y intercept means x=0. f(0)=0-3=-3
g(0)=4
y intercept for f(x) is-3,y intercept for g(x)is 4
Answer:
<h2>
D. aₙ = 5n - 11</h2>
Step-by-step explanation:
The equation of the nth term of the arithmetic sequence is: 
d = 9 - 4 = 5
a₁ = -6
Therefore:
