Answer:
1. Area of a square = (x^2)^2 = x^4
(each side is x^2, area of a square = side^2
so (x^2)(x^2) = x^4 )
2. when x = 5
area = 5^4 = 625
3. when x = 10
area = 10^4 = 10000
Step-by-step explanation:
Hope its right!
Answer: 20%
Step-by-step explanation:
If we let the original amount be x, then after increasing it by 25%, we now have 1.25x
To get this back to x, we need to do 1.25x*(something) = x
this gives us that something = 1/1.25 = 0.8
meaning you need to decrease it by 100% - 80% = 20%
Answer:The answer is 77.
Step-by-step explanation:
But it's not in the options.
If the question is 62-15=47
The equation of the line will be y = -3.9, and the height after rounding off will be -4.
<h3>What is a straight line?</h3>
A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:

The horizontal line can be defined as:
y = a
Where a is the constant.
Here a = -3.9
y = -3.9
The height = -3.9 ≈ -4
Thus, the equation of the line will be y = -3.9, and the height after rounding off will be -4.
