The answer to this question is 9n^2+3n-2. We expand this polynomial factored with the distributive property
(3n-1)(3n+2) = 3n(3n-1)+2(3n-1) = 9n^2 - 3n + 6n - 2 = 9n^2 + 3n - 2

The first step for solving this expression is to multiply each term in the first parenthesis by each term in the second parenthesis (FOIL method)
3n × 3n + 3n × 2 - 3n - 2
Calculate the product of the first two numbers.
9n² + 3n × 2 - 3n - 2
Calculate the product of the next set of multiplication.
9n² + 6n - 3n - 2
Collect the like terms that have a variable of n to get your final answer.
9n² + 3n - 2
This means that the correct answer to your question is going to be 9n² + 3n - 2.
Let me know if you have any further questions.

A line passes through the point (-3, -3) and has a slope of 1/2. What is the equation of the line? A y= 1/2x + 3/2 B y= 1/2x -3/
garik1379 [7]

Answer:

(B.) y= 1/2x -3/2

Step-by-step explanation:

(-3, -3) = (x_1,y_1)\\m = 1/2\\\\y-y_1=m(x-x_1)\\\\y -(-3)=\frac{1}{2} (x -(-3)\\\\y+3 = \frac{1}{2}(x+3)\\\\ y+3 = \frac{1}{2} x+\frac{3}{2}\\\\ y = \frac{1}{2} x +\frac{3}{2} -3\\\\y = \frac{1}{2} x - \frac{3}{2}

Find the gradient of the line Joining the points p(-2,6) and Q(3,-2)​
Rudiy27

Answer:

-  \frac{8}{5}

Step-by-step explanation:

\boxed{gradient =  \frac{y1 - y2}{x1 - x2} }

(x₁, y₁) is the 1st coordinate while (x₂, y₂) is the 2nd coordinate.

Gradient of the line

=  \frac{6 - ( - 2)}{ - 2 - 3}

=  \frac{6 + 2}{ - 5}

=   - \frac{8}{5}

During the school year or each student planted 2 * 10^2 trees as part of a community service project. If there are 3.5 * 10^3 st
Nookie1986 [14]

Total 7*10^5 trees were planted.

Further explanation:

The product of both quantities will give us the total number of trees planted by the students for the community project.

So,

Given

Trees\ planted\ by\ each\ student=2*10^2\\Total\ students\ in\ school=3.5*10^3\\Total\ trees\ planted= (2*10^2)*(3.5*10^3)\\= 7*10^5\ trees

So, total 7*10^5 trees were planted.
