Area of the triangle,
A = bh / 2 = (10 mm)(9 mm) / 2 = 45 mm²
Since there are 2 triangles, their total area is 90 mm².
Then, the area of the sides are,
3A = (3)(10 mm)(18 mm) = 540 mm²
The total area is equal to 585 mm².
There is no answer as d is not defined
False. To find the decimal point while multiplying, count the number of decimal places (to the right of the decimal) in the factors. Then use the total of decimal places and move to the product. Start on the left side, and move the decimal over one number place for each decimal place.
Example: 3.77*2.8=?
3.77
* 2.8
----------
10556
But this is without the decimal point.
3.77 has two decimal places, and 2.8 has one. Put them together and you get a total of three decimal places.
10556, then, should have three decimal places.
Your answer would be 10.556
I hope this wasn't too confusing.
Answer:
C
Step-by-step explaination
C is false since 4^3=8
I believe the first one is p^2-3p+7p-21 and the second one is9a^2-3ab-3ab+b
