Answer:
-1, 1
Negative one and positive one total up with a sum of 0.
-2 + 0 is -2.
0 and 1 is 1.
0 and -1 is -1.
So, it has to be -1 and 1.
Answer: 5040

The formula for a Permutation with duplicates is:
Where
- n: the total number of terms
- a: the number of duplicates for one of the terms
- z: is the number of duplicates for a different term
Since we have a requirement that 2 of the G's must be next to each other, the numerator reflects as:
The denominator will have 3! to represent the G's
and 3! to represent the E's
Solution:
B I think I’m not sure because you did not include the type of prism... rectangular triangular? Also if your talking about lateral surface area! so 400mm squared b I think

Define Length and Width
---------------------------------------------------------------------------------
Let the width be x
Width = x
Length = 2x + 5
---------------------------------------------------------------------------------
Form equation and solve for x
---------------------------------------------------------------------------------
x(2x + 5) = 63
2x² + 5x = 63
2x² + 5x - 63 = 0
<span>(x+7)(2x-9) = 0
</span>x = -7 (rejected, length cannot be negative) or 2x - 9 = 0
2x - 9 = 0
2x = 9
x = 9 ÷ 2
x = 4.5 ft
---------------------------------------------------------------------------------
Find Length and Width
---------------------------------------------------------------------------------
Width = x = 4.5 ft
Length = 2x + 5 = 2(4.5) + 5 = 14 ft
---------------------------------------------------------------------------------
Answer: Width = 4.5 ft , Length = 14 ft
