Answer:

$12n^2-5n-2$

The expression (3n-2)(4n+1) can be factored with the Distributive Property. It cannot be factored with a Least Common Multiple (LCM), for instance, because the terms within each set of parentheses are completely simplified.

Step-by-step explanation:

Part I

. $1. (3n-2)(4n+1)\\2. F.O.I.L.: 12n^2+3n-8n-2\\3. Simplify: 12n^2-5n-2\\$

Good luck to you!

What are the weights (in Newton’s) for the given masses 22.1,33.5,41.3,59.2,78

Blababa [14]

Answer:

1. 216.8 N

2.328.635 N

3. 405.153 N

4. 580.752 N

5. 765.18 N

Step-by-step explanation:

1. Let the mass is 22.1 kg, then the weight in Newton will be (22.1 × 9.81) = 216.8 N {Where acceleration due to gravity is 9.81 m/sec²}

2. Let the mass is 33.5 kg, then the weight in Newton will be (33.5 × 9.81) = 328.635 N {Where acceleration due to gravity is 9.81 m/sec²}

3. Let the mass is 41.3 kg, then the weight in Newton will be (41.3 × 9.81) = 405.153 N {Where acceleration due to gravity is 9.81 m/sec²}

4. Let the mass is 59.2 kg, then the weight in Newton will be (59.2 × 9.81) = 580.752 N {Where acceleration due to gravity is 9.81 m/sec²}

5. Let the mass is 78 kg, then the weight in Newton will be (78 × 9.81) = 765.18 N {Where acceleration due to gravity is 9.81 m/sec²}

Write an equation in slope intercept form that passes through the points ( 3,9) and (4,6)

kobusy [5.1K]

Hello!

To write this equation, let's first find the slope using the formula $\frac{y_{2} - y_{1} }{x_{2} - x_{1}}$ .

Plug in the values

$\frac{6 - 9}{4 - 3}$

Now solve to find our slope.

$\frac{6 - 9}{4 - 3} = \frac{-3}{1}$

<u />Your slope is -3.

Plug that into slope-intercept equation.

$y = -3x + b$

Now we find our y-intercept by plugging in a y-coordinate for the y value in the equation. I'll use 6

$4 = -3x + 6 6 = -3(4) + b

6 = -12 + b 

6/6 = -12/6 + b

-2 = b$

Your y-intercept is -2.

Your equation is y = -3x - 2
