Answer:
4
Step-by-step explanation:
Here you need not completely solve 7992 squared. You can just take the last digit which in this case is 2 and solve for the square of that digit. 2 x 2 = 4. Now if it was a bigger digit which would result in a two digit number when squared you would take the last digit of that number. But, we don't need to do that here since 2 squared is 4.
<h2>
The value of x is always grater than 4.</h2><h3>
Therefore x = (4,∞)</h3>
Step-by-step explanation:
Given
5x+ 2 >3x+10
⇔5x - 3x >10-2
⇔2x > 8
⇔x > 4
<h3>
The value of x is always grater than 4.</h3><h3>
Therefore x = (4,∞)</h3>
Answer:
5
Step-by-step explanation:
rate of change = slope = 5
Let x be the length and y be the width of a rectangle.
Area = xy
When x and y are doubled
Length = 2x and Width = 2y
Area = 2x x 2y
Area = 4xy
-------------------------------------------------------------------------------------------------
Answer: When the dimension is doubled, the area is 4 times the original.

Answer:
D) 5
Step-by-step explanation:
Since 2x = x+5, we have x = 5.
