Hello! -1 - 9 is -10. F = -10. 7 - 9 is -2. G = -2.

F = -10
G = -2
d = 3

Okay, so because d and F are beside each other, we multiply both of the values. Let's plug in the values. -10 * 3 is -30. This is because one negative and one postive make a negative number. Now, we add the number. Because it is negative, we have to go into the negatives more. -30 + (-2) is -32. There. The answer is -32.

Iteru [2.4K]

Answer:

The correct option is 2.

Step-by-step explanation:

According to the the center-of-gravity technique, the coordinates of the center-of-gravity location are

(\frac{\sum x_iL_i}{\sum L_i},\frac{\sum y_iL_i}{\sum L_i})

Where ((x_i,y_i) represent the coordinates and L_i is demand.

We have to find the Y-coordinate of the center-of-gravity location.

The sum of product of demand and corresponding y coordinates is

\sum y_iL_i=65\times 2200+55\times 900+95\times 1300+200\times 1750+175\times 3100=1208500

The sum of demanded units is

\sum L_i=2200+900+1300+1750+3100=9250

The Y-coordinate of the center-of-gravity location is

y_0=\frac{\sum y_iL_i}{\sum L_i}

y_0=\frac{1208500}{9250}

y_0=130.6486

y_0\approx 131

The Y-coordinate of the center-of-gravity location is 131. Therefore the correct option is 2.

Which expression is equivalent to (6y^2-2)(6y+2)
ivann1987 [24]

Answer:

6y^3 + 12y^2 - 12y - 4

Step-by-step explanation:

So, you would multiply each in first equation for the second equation, you will got:

= 6y^2 * 6y + 6y^2 * 2 - 2*6y - 2* 2

= 6y^3 + 12y^2 - 12y -4

This would be the final expression

Hope this help you :3
