Question : The expression (22
+ 9) can be factored using the difference of squares rule.
True
False

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
