Number 18 and 20 thank you
Afina-wow [57]
18.) The area of one of the triangles would be half of the area of the parallelogram, because the two triangles are congruent.

20.) The formula for the area of a parallelogram is:
A = b • h

110.5 = 13h

110.5 / 13 = 8.5

110.5 = 13 • 8.5

And because this is a measurement of the height, not the area, it is just meters (m)

So, the full answer is 8.5 m

I hope this helps!

Answer:

| 10  -10  1  |

|  1    -2  -4 |

| -8  13 -24|

Step-by-step explanation:

First multiply each element in matrix A, this gives:

| -6  - 2  -3 |

|  1   -6   -4 |

| -4   5    0 |

Now we multiply each element in matrix B by  4, this gives:

| -16  8  -4 |

|  0   -4  0  |

|  4  -8  24 |

Finally subtract  this from the first matrix ( subtracting element by element) gives:

| 10  -10  1 |

|  1    -2  -4|

| -8   13- 24|

sineoko [7]

Answer:

Step-by-step explanation:

x² - y² =  (x + y)(x-y)

c² - (5b - 3a)² = (c + [5b -3a]) ( c - [5b - 3s] )

                     = (c + 5b - 3a) (c - 5b + 3s)
