Answer: 4 cm and 11 cm.
Step-by-step explanation:
1. You can calculate the perimeter of a parallelogram as following:
Where a+b+c+d are the lenghts of the sides.
By definition the parallelogram has two pairs of parallel sides, therefore:
a=c and b=d
Then, you can calculate the perimeter as following:
2. Let's call the adjacent side , then the other side is 2x+3.
3. Substitute values and solve for x:
4. Then the lenghts of the sides are:
B I’m pretty sure sorry if wrong
Answer:
300
Step-by-step explanation:
Since the number in the tenths place is five or greater, 270 3/12 rounds up to 300.
Note: The 3/12 is null because whether it would round the number or down would not affect the 270. (271 would still round up to 300)
Answer:
The answer to this would be 512
Step-by-step explanation:
All you have have to do is multiply each of them by 4. That is the pattern to this. Grab your calculator and try it for yourself. You will see that 2x4=8
8x4=32 32x4=128 128x4=512. Hope this helps :)
