Answer:
Step-by-step explanation:
(0.4)^3= (0.4)(0.4)(0.4)= (0.16)(0.4)= 0.064
the answer is D

I hope helped ^-^
Answer:
They are not equal to each other
Step-by-step explanation:
3^2 + 2^2 = C^2
9+4=C^2
13=c^2
3.6= CD
2^2 +2^2 =c^2
4+4 =c^2
8=c^2
2.8= EF
Solution: (2,8)
Using the elimination method set up the system of equations like:
y = x + 6
y = 3x + 2
Eliminate the x-variable by multiplying the top equation by -3
-3y = -3x -18
y = 3x + 2
Combine terms:
-2y = -16
-y = -8
y = 8
Plug in 8 to one of the first equations for y
8 = 3x + 2
6 = 3x
x = 2
Solution: (2,8)
8x - 13 = x + 1
Solve for x
Add 13
8x = x + 14
Subtract x
7x = 14, x = 2
Answer: the number is 2
