(−6)∙(a+2b−3c−4d)−(−2)∙(−4a−3b+2c+d)
this will give us:
-6(a+2b-3c-4d)+2(-4a-3b+2c+d)
opening the parenthesis we get:
-6a-12b+18c+24d-8a-6b+4c+2d
putting like terms together we get
-6a-8a-12b-6b+18c+4c+24d+2d
simplifying the above we get
-14a-18b+22c+26d
the answer is :
</span>-14a-18b+22c+26d<span>

A stock lost 8 1/4 points on Monday and then another 2 3/4 points on Tuesday. On Wednesday, it gained 12 points.
o-na [289]

The net gain of the stock for these three days is 1 points

<h3>Net gain</h3>

  • Monday = - 8 1/4 points
  • Tuesday = -2 3/4 points
  • Wednesday = 12 points

Net gain / net loss = Monday + Tuesday + Wednesday

= - 8 1/4 + (-2 3/4) + 12

= - 8 1/4 - 2 3/4 + 12

= -11 + 12

Net gain = 1 point

Therefore, the net gain of the stock for these three days is 1 points

What is the area of the figure?
finlep [7]

Answer:

Option C

A = 390 cm ^ 2

Step-by-step explanation:

The image shows a figure composed of a rectangle and a triangle.

We know that the area of a rectangle is:

Ar = length * width

Then, using the data shown in the image, we have to:

Ar = 20(15) = 300 cm ^ 2

Then, the area of a triangle is:

At = \frac{1}{2}base*height

So:

At = \frac{1}{2}15(12)

At = 90\ cm ^ 2

Finally the area of the figure is:

A = At + Ar\\\\A = 390\ cm ^ 2

Hich value, when placed in the box, would result in a system of equations with infinitely many solutions?
Jobisdone [24]

The value placed in the box that makes the system of equation with infinitely many solution is 12.

<h3>How to solve an infinitely many solution equation?</h3>

An infinite solution has both sides equal. For example, 6x + 2y - 8 = 12x +4y - 16.  If we simplify the equation we will notice both sides are equal. This means the equation has an infinitely many solution.

Hence,

y = -2x + 4

Therefore,

6x + 3y = 12

divide the equation(ii) by 3

2x + y = 4

y = -2x + 4

Therefore, both equation are equal if the the box is filled with 12. This means for the value placed in the box that makes the system of equation with infinitely many solution is 12.
