-3(4-2y)=24
Apply distributive property
-12+6y=24
Add 12 to both sides
6y=36
Divide both sides by 6
y=6
Answer:
Total surface = 102.4 cm^2 (second answer in the list of options)
Step-by-step explanation:
Notice that we need to add the surface of 4 rectangles, two have smaller sizes than the other two. A pair of rectangles are 7.2 cm x 4 cm = 28.8 cm^2, while the other pair has 7.2 cm x 2 cm = 14.4 cm^2
There are also two equal bases each one of size 4 cm x 2 cm = 8 cm^2
Now we add two of each of the individual surfaces discussed above to complete the total surface area:
2 * 28.8 + 2 * 14.4 + 2 * 8 = 102.4 cm^2
which agrees with the second answer option provided.
Answer:

<u>Given</u>:
The given circle with center at C. The lines AB and AD are tangents to the circle C.
The length of AB is (3x + 10)
The length of AD is (7x - 6)
We need to determine the value of x.
<u>Value of x:</u>
Since, we know the property of tangent that, "if two tangents from the same exterior point are tangent to a circle, then they are congruent".
We shall determine the value of x using the above property.
Thus, we have;
AB = AD
Substituting the values, we get;
![3x+10=7x-6](https://tex.z-dn.net/?f=3x%2B10%3D7x-6)
Subtracting both sides of the equation by 7x, we get;
![-4x+10=-6](https://tex.z-dn.net/?f=-4x%2B10%3D-6)
Subtracting both sides of the equation by 10, we get;
![-4x=-16](https://tex.z-dn.net/?f=-4x%3D-16)
Dividing both sides of the equation by -4, we get;
![x=4](https://tex.z-dn.net/?f=x%3D4)
Thus, the value of x is 4.
85/95 is equal to 0.8947
64/76 is equal to 0.842
Therefore, 85/95 is greater
