Answer:
A) 6Gn + 12 (or 6n+12, if that’s what you meant)
B) 4p²+9p
C) 5r²+20r
Step-by-step explanation:
A. If you meant 6(n+2)...
Multiply 6 by n and also 6 by 2:
6n + 12
B. Multiply p by 4p and also p by 9
4p²+9p
C. Multiply 5r by r and also 5r by 4
5r²+20r
Hope this helped!

Answer:
1. 10C4 = 210
2. 4C1 + 10C1 = 14
Step-by-step explanation:
There are total 4 types of cakes available. Chocolate, cherry, apple and plain cakes. If we select 10 cakes, the possibility that at least 1 cake is selected for every variant is 210. We use computation technique in statistics for this purpose 10C4. After calculation we get 210.
If we select 4 apple cakes and one chocolate cake then there will be 14 different ways to do this. It is assumed that the order does not matter.
It has 9 perpendicular lines.
Answer:the length of the rectangle is 36 feet
Step-by-step explanation:
Let L represent the length of the rectangle.
Let W represent the width of the rectangle.
The length of a rectangle is equal to three times its width. This means that
L = 3W
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
If the perimeter is equal to 96
feet, it means that
2(L + W) = 96
L + W = 96/2 = 48
Substituting L = 3W into L + W = 48, it becomes
3W + W = 48,
4W = 48
W = 48/4 = 12
L = 3W = 3 × 12 = 36
