Answer:
<h2><u><em>
Area = x² + 8x + 12</em></u></h2><h2><u><em>
Perimeter = 4x + 16</em></u></h2>
Step-by-step explanation:
The area of a rectangle is given by the formula:
Area=width×height
The perimeter of a rectangle is given by the formula
Perimeter=2(width+height)
Area
(x + 6) × (x+2) =
x² + 2x + 6x + 12
x² + 8x + 12
------------------
Perimeter
2 × (x + 6 + x + 2) =
2 × (2x + 8) =
4x + 16

The answer to the question is C.
Answer:
Yes, after 10 key presses, both will arrive at the number 30.
Step-by-step explanation:
The difference between the numbers on the calculators is reduced by 10 with each key press. After 10 key presses, the initial difference of 100 will be zero. After 10 key presses of (-7), the calculator starting at 100 will be ...
100 +10(-7) = 30
After 10 key presses of (+3), the calculator starting at 0 will be ...
0 +10(+3) = 30
Both calculators will show 30 after 10 key presses.
