Answer:
It's 70.4 because i subtracted the 2 numbers and it gave me 9.6 just like 80-9.6. I don't know if i'm right, please correct me if i'm wrong. I'm still not sure...
Step-by-step explanation:
43-123= -80
80-9.6=70.4
80-70.4= 9.6
4x+6 (3x ) - 12 = 4x +6 *3 x - 12
= 4x +18 x - 12
= 22 x -12
Answer:
X = 3
Step-by-step explanation:
3^3 = 9, 9^3 = 27.
Answer: a) -6, b) 32, c) -48, d) 9, e) -12
Step-by-step explanation:
Since we have given that
A and B are 4 × 4 matrices.
Here,
det (A) = -3
det (B) = 2
We need to find the respective parts:
a) det (AB)

b) det (B⁵ )

c) det (2A)
Since we know that

so, it becomes,

d) 
Since we know that

so, it becomes,

e) det (B⁻¹AB)
As we know that

so, it becomes,

Hence, a) -6, b) 32, c) -48, d) 9, e) -12
I might be wrong but 9
9*2=18
18+7= 25
25 square root = 5
Answer is 9
