Answer:
D. 8
Step-by-step explanation:
The given diagram is a trapezium. We know that the consective sides of a trapezium are equal. so,
Putting the values of consecutive sides equal:
So, KI will be equal to LI
3x-7 = x+3
![3x-7-x=x+3-x\\2x-7=3\\2x-7+7=3+7\\2x=10\\x=5](https://tex.z-dn.net/?f=3x-7-x%3Dx%2B3-x%5C%5C2x-7%3D3%5C%5C2x-7%2B7%3D3%2B7%5C%5C2x%3D10%5C%5Cx%3D5)
Putting the value of x in the equation of KI
3x-7
=3(5)-7
=15-7
=8
Hence, the correct answer is D. 8 ..
You need to create a chart like the one attached and put your own values in it. The teacher wants atleast 3 inputs and outputs but 4 or 5 is better. You first need to create a rule (EX: x+1=y)
If you are trying to get the answer to
![\frac{3}{7} + \frac{8}{2} ](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B7%7D%20%2B%20%20%5Cfrac%7B8%7D%7B2%7D%20%0A)
Your answer would be a mixed number.
