To calculate the perimeter of a rectangle what you would do is add the parallel sides together so 11+11=22 and then 4+4=8 so we would add 22+8=30

So your answer would be 30

Solution:

Simplify the equation and solve for r.

r/16 + 6 = 7
=> r/16 = 7 - 6
=> r/16 = 1
=> r = 16

The value of r is 16.

Check:

r/16 + 6 = 7
=> 16/16 + 6 = 7
=> 1 + 6 = 7
=> 7 = 7 (Proved correct)

Column A

Viefleur [7K]

The slope m of a line passing through points P(a, b) and Q(c, d) is found using the formula:

$m= \frac{b-d}{a-c}$ .

Thus, the slope in A is $m= \frac{12-2}{-4-(-10)}=\frac{10}{6}=\frac{5}{3}$ .

The slope in B is $m= \frac{-4-10}{6-18}=\frac{-14}{-12}=\frac{7}{6}$ .

Now, to compare 7/6 to 5/3, we can write the second fraction as 10/6.

So, the slope in A is larger than the slope in B.
