Well since you already completed the table, a pattern would be that the left column is twice the amount of the right column ( 30x2=60, 35x2=75,etc.)
The answer would be D- looks. All the other options are nouns and adjectives.
X^2 + 16x + 64
= (x + 8)^2
length of the side = 25+8 = 33 feet
- 4x^2y * 3xy^3
multiply the numbers : 4*3 = 12
-12x^2xy^3y
apply exponent rule : x^2x = x^2+1 = x^3
-12x^3y^3y
apply exponent rule again : y^3y = y^1+3 = y^4
answer : -12x^3y^4
