Answer:
(x + 9)(x + 3)
Step-by-step explanation:
Factor 27 so that the factors, when combined, will equal 12:
x² + 12x + 27
x 9
x 3
(x + 9)(x + 3) is your answer.
Check: Use the FOIL method. Multiply the first two terms, the outside terms, the inside terms, and then the last two terms. Combine like terms:
(x + 9)(x + 3) = x² + 3x + 9x + 27 = x² + 12x + 27 (√)

Answer:
Similar - Top center, bottom left
Not similar, different shape - Top left, bottom right
Not similar, different ratio of side lengths - Top right, bottom center
Step-by-step explanation:
We can see automatically that the top left and bottom right are not similar because they are a triangle and a trapezoid, not a rectangle.
Top right is not similar because of its different ratio of sides. The ratio for the sides of the original rectangle is 3:7, while the ratio of the top right is 2:3.5 .
Bottom center is not similar because of its different ratio of sides as well, as its ratio is 6:12
