The value of the length of BC is 45 units
The given parameters are:
BC = 15x
AD = 32x - 2
EF = 20.5x + 8
Where the parallel bases are AD and BC and the midsegment is EF
By the midsegment theorem, we have
2 * EF = AD + BC
Substitute the known values in the above equation
2 * (20.5x + 8) = 15x + 32x -2
Open the bracket
41x + 16 = 15x + 32x - 2
Evaluate the like terms
6x = 18
Divide both sides by 6
x = 3
Substitute x = 3 in BC = 15x
BC = 15 * 3
Evaluate
BC = 45
Hence, the value of the length of BC is 45 units

Answer:
5/12, 6/13, 13/28, 10/17, 2/3
Step-by-step explanation:
First, simplify the ones that could be simplified.
2/3, 5 to 12, 6:13, 10:17, 13/28
<em>(okay apparently only the first could be simplified)</em>
<em />
You can look at all of them as fractions
2/3, 5/12, 6/13, 10/17, 13/28
Answer:91 i think
7.22 x 10^5
Remember that the decimal is always to the right of the ones place.
1. Move it one place to the left and multiply by 10 to compensate.
2. Move it two places to left and multiply by 10^2.
3. Move the decimal point three times and multiply 10^3 to compensate, and the pattern continues until you reach the very last digit, the 7.
4. Numbers after the 7 that are not zeros will be after the decimal point.
so, 7.22 x 10^5
