Mathematics

Answer:

32x^3 + 4x^2  + 41x - 35

Step-by-step explanation:

Multiply each of the terms in bracket 1 with those in bracket 2.

4x^2 x 8x = 32x^3

4x^2 x -5 = -20x^2

3x x 8x = 24x^2

3x x -5 = - 15x

7 x 8x = 56x

7 x -5 = -35

Now, put them together and simplify:

32x^3 - 20x^2 + 24x^2 - 15x + 56x - 35

After simplifying:

32x^3 + 4x^2  + 41x - 35

Answer:

x = 4.

Step-by-step explanation:

I am assuming that you want to find the values of x and that WXYZ is a parallelogram.

In a parallelogram opposite sides are equal, therefore:

11x + 1 = 19x - 31

1 + 31 = 19x - 11x

32 = 8x

x = 32/8 = 4.

I'm stuck on this question, please help. Thank you!!! ​
anastassius [24]

Let's multiply each of the four squares, one by one.

In blue, we see the dimensions are x by x.  x times x = x^2

In pink, we see the dimensions are 9 by x.  x times 9 = 9x

In green, the dimensions are x by 3.  3 times x = 3x

And finally, yellow's dimensions are 3 by 9.  3 times 9 = 27

We can now just add all these areas to find the total area:

x^2 + 12x + 27
