(4^-1/2^-2)^2
= 4^(-1*2) / 2^(-2*2)
= 4^-2 / 2^-4
= 2^4 / 4^2
= 16 / 16
= 1
Answer:
we can describe the parts of the expression that the arrows
point to 3x-2 such as:
↑(x variable)
← (2 constant)
↓
(3 coefficient)
Step-by-step explanation:
Given the expression
- As we have to describe the parts of the expression the arrows
point to .
we can describe the parts of the expression that the arrows
point to 3x-2 such as:
↑(x variable)
← (2 constant)
↓
(3 coefficient)
Therefore, it is clear that:
- The upper arrow '↑' points to the variable part 'x' of expression which is 'x'.
- The lower arrow '↓' points to the coefficient part of the expression which is '3'.
- The arrow '←' points to the constant part of the expression which is '2'.
3x-r=-3r+rx
3x=-3r+r+rx
3x=-2r+rx
3=rx-2r/x
there you go buddy...gitty up
Answer:
length= 42 cm width= 21
Step-by-step explanation:
let x= the width and 2x= the length
x+x+2x+2x= 126
solve for x
x=21
