Answer:
D
Step-by-step explanation:
Given
- 4(x - 6) + 3(a - 7)
distribute the first parenthesis by - 4 and the second by 3
= - 4x + 24 + 3a - 21
= - 4x + 3a + 3 → D

Answer:
The volume of a sphere is 2/3 times the volume of a similar cylinder
Scale factor : 2/3
Step-by-step explanation:
Let us consider a sphere of radius r. The volume of the sphere will be given as

Similarly, let us consider a cylinder with its height being twice the radius of the sphere. We will have its volume given as:

but h = 2r
Hence we have

We can divide the two volumes to get a constant that links them together

this will give us 2/3
Hence the scale factor for Vol sphere: Vol cylinder is 2/3
