Answer:
(x² + 18) units²
Step-by-step explanation:
Area of a rectangle = l*w
There are two shaded rectangles found inside the large rectangle. Let us represent the smaller shaded one as Rectangle 1, the bigger shaded rectangle as Rectangle 2.
Below are the dimensions and area if each of them:
Rectangle 1 (small shaded rectangle):
l = x
w = x
Area = x * x = x² units²
Rectangle 2 (bigger shaded rectangle):
l = 9
w = 2
Area = 9*2 = 18 units²
Total area of the shaded rectangles = x² + 18 = (x² + 18) units²
The bottom next number is -2.28 and the equation becomes , where n is the input value and O is the output value.
Step-by-step explanation:
The given values are,
Input Output
1 2
2 0
3 -2
4 -4
?
Step:1
Based on the input and output values assume the equation,
.....................(1)
Where,
n - Input values
O - Output values
Step:2
Check for solution,
Take, n = 1
O = 2 ( 2 - 1 )
= 2 ( 1 )
O = 2
Take, n = 2
O = 2 ( 2 - 2 )
= 2 ( 0 )
O = 0
Take, n = 3
O = 2 ( 2 - 3 )
= 2 ( -1 )
O = -2
Take, n = 4
O = 2 ( 2 - 4 )
= 2 ( -2 )
O = -4
Now, we substitute the value for n = ,
Take, n =
O = 2 ( 2 - )
= 2 ( 2 - 3.14 ) ( ∵ = 3.14 )
= 2 ( -1.14 )
O = -2.28
Result:
The bottom next number is -2.28 and the equation becomes , where n is the input value and O is the output value.

Step-by-step explanation:
Answer:
The salesman sold 56 large appliances.
Step-by-step explanation:
$57,400 - $35,000 = $22,400
He made $22,400 off the appliances.
To find how many appliances, you can divide 22,400 by 400.
The equation should be ($57,400 - $35,000)/400 = x
Here x represents the amount of large appliances sold. If you run the equation, the answer you should get is 56.
Answer:
C
Step-by-step explanation:
We know that function <em>h</em> represents an object's height in feet after <em>x</em> seconds.
In that case, option A) h(15) = 100 means that after 15 seconds, the object's height is 100 feet.
Option B) h(100) = 15 means that after 100 seconds, the object's height is 15 meters.
Therefore, neither A nor B are correct.
Option C) h(15) - h(0) = 100 means that between the zeroth and 15th second, their difference is 100 feet.
In other words, the object's height increased by 100 feet over the first 15-second period.
Option C is correct.
For Option D), it gives us the average rate of change. (h(15) - h(0)) / (15) = 100 means that for the first fifteen seconds, the height of the object increased at an average rate of 100 feet per second.
