Mathematics

Answer:

  see attachment

Step-by-step explanation:

The directions tell you what you need to know. It is a matter of adding up the values shown and finding the missing number to make the total be -20. Of course, it works best to start with a row, column, or diagonal that has 4 numbers already.Then, you're only finding the 5th number.

You can start with either diagonal, column 1 or 4, and row 4 or 5. Filling the missing numbers in those spots (red) will let you find the remaining missing numbers (green, then blue).

The square at row 2, column 2 can be filled on the first round using the down-right diagonal. I have shown it as filled on the second round after row 5 column 2 is filled.

Using a spreadsheet can make this easier, because you can write formulas for the sums in each row, column, and diagonal. Then you're just making those sums be -20.

___

For example, consider the up-right diagonal. The sum of the given values, -6, 0, -4, -2, is -12. Then the spot at row 1, column 5 must be filled with -8 to make the sum be -20.

What would the total area be??
timurjin [86]

Answer:

1,560,000 mm²

Step-by-step explanation:

A= \frac{(1600*600)}{2} This would make shape A's area <u>480,000</u>.

B= \frac{(600*600)}{2} This would make shape B's area <u>180,000</u>.

C= \frac{(1000*600)}{2} This would make shape C's area <u>300,000</u>.

D= 1000×600 This wouls make D's area <u>600,000</u>.

Now you add up all of the areas;

480,000+180,000+300,000+600,000= 1,560,000 mm²
