Answer : 12
Explanation :
In the first row of the table, we find that the -2 is the change, and in the third row -6 is the change.
Using this, we can find that the second row should have -4 subtracted from 16.
We know this because from looking at the changes from the first and second row, the differences multiply by two, as the rows increase. So -2 multiplied by 2 is -4, and 16 subtract 4 is 12.
Answer:
Step-by-step explanation:
For the sake of clarity, assuming you meant:
1) Absolute Value or Modulus functions has one property that assures us that:
2) Solving for x
Not defined in Real Set of Numbers
Evaluating :
3) So, since for the first case the Discriminant Δ <0, then the solutions presented for . The only solution in the Real Set for the inequality is , i.e. x=-1.
Answer:
61 coins that are not nickels
n = 82 - 61
Step-by-step explanation:
22 pennies + 23 dimes + 16 quarters = 61 coins that are not nickels
n = no. of nickels
n = 82 - 61
Hello There!
The length of the hypotenuse is 10.
We know what 2 sides are 6 and 8.
To find the third side we use the formula a^2 + b^2 = c^2
So we multiply 6 by 6 which equals 36 and then multiply 8 by 8 which equals 64.
Next we add 64 and 36 together and we get 100.
Next, we square root 100 and get 10.
10 is the length of the hypotenuse.
The expression that can be used to find the area of the tiled floor is 4w² + 200w
<h3>Area of rectangle</h3>
Length = 70 Meters
Width = 30 meters
Area = length × width
= 70 × 30
= 2100
- New rectangle(including tiled floor):
Length = 70 + 2w meters
Width = 30 + 2w meters
Area = length × width
= (70+2w) (30+2w)
= 2100 + 140w + 60w + 4w²
= 4w² + 200w + 2100
Area of the tiled floor = Area of new rectangle - area of old rectangle
= (4w² + 200w + 2100) - 2100
= 4w² + 200w + 2100 - 2100
= 4w² + 200w
