Answer: B. 30
Step-by-step explanation:
First, you re-write the expression
6(-3.5) + 15(4) - 12(3/4)
Then multiply all the parts correctly.
-21 + 60 - 9
-21 + 60 = 39
-9
= 30
Answer: 4
Step-by-step explanation:
We know that a plane is 2 dimensional surface that extends infinitely far.
The number of points required to define a plane = 3
Here , we have 4 points A, B, C, and D.
So, the number of possible combinations of 3 points to make a plane from 4 points = 
[
]
Hence, the greatest number of planes determined using any three of the points A, B, C, and D if no three points are collinear = 4.
2X-2=2X+9
Add 2
2X=2X+11
Subract 2X
0= 11
This has no solution to this problem
A.
let the number be n.
2n+5=45
2n=40
n=20
