Answer:
27.5
Step-by-step explanation:
first you find what 30x30 is as A squared plus B squared is equal to C squared. your A is 12 and your C is 30.
so!
30x30 is 900
12x12 is 144
subtract 144 from 900 and you get 756. once you find the square root you get 27.49. then round up to 27.5
C. As that’s the same as 15>8.

Step-by-step explanation:
Answer:
b) -18(2x -3y + 5)
d) 18(-2x + 3y - 5)
e) -2(18x - 27y + 45)
Step-by-step explanation:
a) -9( 4x - 6y - 10) = -36x + 54y + 90 not equal
b) -18(2x - 3y + 5) = -36x + 54y - 90 equal
c) -6(6x + 9y - 15) = -36x - 54y + 90 not equal
d) 18(-2x + 3y - 5) = -36x + 54y - 90 equal
e) -2(18x - 27y + 45) = -36x + 54y - 90 equal
f) 2(-18x + 54y - 90) = -36x + 108y - 180 not equal
