Step-by-step explanation:

l = 3x - 5

w = 2x + 9

perimeter = 2l + 2w = 2(3x - 5) + 2(2x + 9) =

= 6x - 10 + 4x + 18 = 10x + 8

area = l×w = (3x - 5)(2x + 9) = 6x² + 27x - 10x - 45 =

= 6x² + 17x - 45

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.
