(=-27) because that’s the end answer
height,h = 3"
base, b = length, l = 2
area of triangle, t = bxh/2...eqn 1
area of square, s = l^2...eqn 2
area of pyramid, p =4t + s...eqn 3
subst h = 3 and b = 2 in eqn 1
t = 3x2/2 = 3
subst l =2 in eqn 2
s = 2^2 = 4
subst t = 3 & s = 4 in eqn 3
p = 4(3) + 4 = 16sq inch

Answer:
(a) 720 ways
(b) 120 ways
(c) 24 ways
Step-by-step explanation:
Given

--- number of letters
Solving (a): Number of arrangements.
We have:

So, the number of arrangements is calculated as:

This gives:

This gives:


Solving (b): DA as a unit
DA as a unit implies that, we have:
[DA] N C E R
So, we have:

So, the number of arrangements is calculated as:

This gives:

This gives:


Solving (c): NCE as a unit
NCE as a unit implies that, we have:
D A [NCE] R
So, we have:

So, the number of arrangements is calculated as:

This gives:

This gives:


I believe the answer is -6.3
my explanation is because -6.3 is less than -6.1 so technically it makes it smaller. if you were to add to -6.3 you would get -6.1 on the x axis.
