the perimeter is 68.8cm
Ok so because this is a rectangle the line directly across (paralell) is equal, so if one line is 16cm, the line parallel to that will also be 16. Then the formula for area is LxW we'd plug in the numbers we know to get 294.4
=16 x W
then we divide 16 by both sides to make it even to get 18.4cm=W. Now we just plug everything in to the perimeter by doing 16 x 2 + 18.4 x 2 to get
For this case we must represent the following expression algebraically:
"eight more than the product of a number and two"
Let "x" be the variable that represents the unknown number
We have to:
the product of a number and two is represented as: 
Then, the full expression will be:
Thus, we use multiplication and addition.

Option C
Answer:
42 units
Step-by-step explanation:
If R is the midpoint of QS, then by definition, QR = RS. Since QR = 8x - 51 and RS = 3x - 6, set these equal to solve for x:
QR = RS
8x - 51 = 3x - 6
5x = 45
x = 9
Now that we know x = 9, we can plug this back into one of the expressions for QR or RS to find its length:
QR = 8x - 51 = 8 * 9 - 51 = 72 - 51 = 21
Since half of QS is 21, then the whole of QS is twice that:
2 * 21 = 42
The answer is thus 42 units.

an = 2n
1 = 2(1) = 2
2 = 2(2) = 4
3 = 2(3) = 6
4 = 2(4) = 8
so, the first four terms are 2 , 4 , 6 , 8.
