Answer:

12

Step-by-step explanation:

If z = 6 and d = 7, we can fill them in the variables. Let's rewrite the expression:

-3([ 2 × 6 ] - [ 8 × 7])

Let's start with the stuff inside the brackets. 2 × 6 minus 8 × 7. We know 2 × 6 = 12, and 8 × 7 = 56.

Then we have -3( 12 - 56 )

We then have to do 12 - 56, which gets us -44.

We now have -3( -44 ) or -3 × (-44)

-3 × (-44) = 12

Thus, we get our final answer of 12.

Hope this helped!

1. -3(2z-8d) Solve within the parenthesis.

2. 2(6)=12, 8(7)=56

3. Do the math within the parenthesis with our new integers. 12-56=-44

4. multiply both integers now. -3(-44) = 132

*a negative times a negative wil give you a positive answer.

Find the value of x for which ABCD must be a parallelogram.
Korvikt [17]

Answer:

x = \frac{5}{3}

Step-by-step explanation:

<u>Parallelogram</u>

It's a quadrilateral formed by two pairs of parallel sides. The opposite sides have equal lengths.

We are given a parallelogram with opposite sides of 3x+1 and 6x-4. They must be equal, thus:

6x - 4 = 3x + 1

Subtracting 3x:

3x - 4 = 1

Adding 4:

3x = 5

Dividing by 3:

\mathbf{x = \frac{5}{3}}

Hey can you please help me posted picture of question
Temka [501]
The correct answer  for the problem shown in the figure atttached is the last option (option D), which is shown below:

 D.(-x-9i)(x-9i)

 If you want to verify that the option D.(-x-9i)(x-9i) is the correct answer, you can apply the distributive property to (-x-9i)(x-9i).

 Therefore, when you apply the distributive property, you obtain that the result is:

 -x²-81

 The graph attached shown this equation, which is a parabola.
