Answer:
Step-by-step explanation:
132 + (4x - 10) + (5x - 11) + 128 + (4x+2) = 540 All convex 5 sided figures have 540 degrees. Remove the brackets.
132+ 4x - 10 + 5x - 11 + 128 +4x + 2 = 540 Collect like terms
13x + 241 = 540 Subtract 241 from both sides.
13x = 540 - 241
13x = 299 Divide by 13
x = 299/13
x = 23
<P = 4x + 2
<P = 92 + 2
<P = 94
Answer:
yes it is a parallelogram
Step-by-step explanation:
it is a parallelogram as opposite sides are equal and parallel
The least common multiple of 9, 3, and 18 is 18.
Convert 1/9 to 2/18.
Convert 2/3 to 12/18.
Then add the numerators:
2 + 12 + 5 = 19
So the answer is 19/18, or 1 1/18 if you prefer.
Answer:
-24
Step-by-step explanation:
multiply, the sign of the product is the sign of the larger number
We would find the mean. So:
15 + 12 + 17 + 13 + 20 + 19 = 96
Divide the sum by the amount of numbers added together.
So: 96/ 16
The mean or average is 16
