Answer: -15p + 41q

Step-by-step explanation:

Problem: -9(4p-6q) + 8q- 7(3q - 3p)

1. Expand by distributing terms

−(36p−54q) + 8q − 7(3q − 3p)

2. Expand by distributing terms

−(36p−54q) + 8q − (21q − 21p)

3. Remove parenthesis

−36p + 54q + 8q − 21q + 21p

4. Collect like terms

(−36p + 21p) + (54q + 8q − 21q)

5. Simplify

-15p + 41q

This polynomial does not factor so you have to complete the square or use Quadratic formula.
x^2 + 6x + 7 = 0
Using completing the square, subtract 7 from both sides.
x^2 + 6x = -7
divide 6 by 2 = 3, square 3 = 9, add 9 to both sides.
x^2 + 6x + 9 = 2
(x + 3)^2 = 2
Take the sqrt of both sides
x + 3 = + - sqrt 2
subtract 3 from both sides
x = - 3 + - sqrt 2
This is not an answer choice but it is the correct answer. You either typed the choices incorrectly or the equation incorrectly.

The function f(x)=1+1.5ln(x+1) models the average number of free-throws a basketball player can make consecutively during practi

UNO [17]

Answer:

402 days.

Step-by-step explanation:

f(x)=1+1.5ln(x+1)

When f() = 10 we have:

10 = 1 + 1.5ln (x + 1)

ln (x + 1) = (10-1) / 1.5 = 6

x + 1 = e^6
