Answer:
D) 20
Step-by-step explanation:
Ml║ YK and YM║KL ⇒ YK= ML= 10
ML║KX and XL║KM ⇒ KX= ML=10
YX= YK + KX= 10+10= 20
YX= 20
Answer:
9 and 11
Step-by-step explanation:
9 and 11 are before and after 10. so, 10 lies between them.
<span>The fraction of baked goods not sold is 6/10. The numerator is the number of left over baked goods (10-4 -6) and the denominator is the total loaves of bread (10). An equivalent fraction is 12/20. This was obtained by multiplying the original fraction by two (6 x2 = 12 and 10 x2 =20).</span>
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:

For this case we have a function of the form
Where:

We must find the value of the function when the variable x is -5.
Then, substituting, 

We have that by sign law
