Answer:
3.75
Step-by-step explanation:
Set up the following ratio:
2400 watt-hours 1 day
------------------------- = ----------
9000 watt-hours x days
Then do criss-cross-apple-sauce:
x*2400=9000*1
And then solve for x:
2400x=9000
x=9000/2400
x=3.75
The value of the expression ((-3)^4)^2 when simplified is 6561
<h3>What are expressions?</h3>
Expressions are mathematical statements represented by numbers, arithmetic operations and variables
<h3>How to simplify the expression?</h3>
The expression is given as:
((-3)^4)^2
Start by expanding the inner bracket
((-3)^4)^2 = ((-3)*(-3)*(-3)*(-3))^2
Next, we evaluate the product (-3)*(-3)*(-3)*(-3)
This gives
((-3)^4)^2 = (81)^2
Next, expand the exponent
((-3)^4)^2 = (81) * 81
Next, we evaluate the product
This gives
((-3)^4)^2 = 6561
Hence, the value of the expression ((-3)^4)^2 when simplified is 6561

Answer:
7(7x-4)
Step-by-step explanation:
We can factor a 7 from each term
49x = 7*7x
28 = 7*4
49x -28
7(7x-4)
