Answer:

9x^2 + 9x -70

Step-by-step explanation:

Use the distributive property to solve

(3x-7) (3x+10)

multiply 3x x 3x = 9x^2

multiply 3x(-7) and 3x(10)

add -21x + 30x = 9x

multiply -7 x 10 = -70

The polygons are similar. Find x and y. The images are not drawn to scale.
Alja [10]
The correct answer to this question is letter "D. x = 21, y = 14."
18 : 12
27 : x - 3
24 : y + 2

18 / 12 = 27 / x - 3
3  / 2 = 27 / x - 3
54 = 3x - 9
3x = 54 + 9
3x = 63
x = 21

18 / 12 = 24 / y + 2
3  / 2 = 24 / y + 2
48 = 3y + 6
3y = 48 - 6
3y = 42
y = 14
