Answer:
E. x² + 11x - 42 = 0
Step-by-step explanation:
let the square sides be x
A = bh = (x + 3 + 3)(x + 2 + 3) = 72
(x + 6)(x + 5) = 72
x² + 11x + 30 = 72
x² + 11x - 42 = 0
Answer:
35
Step-by-step explanation:
For this question do 27 squared which is 729 + 22 squared which is 484 then add them to get 1213 then square root 1213 to get 34.8281495345 which rounded to the nearest inch would be 35
The answer is 3 :) hope this is right
Y^9-y^3 can also be written as y^9-y^3=x
so it is also equivalent to x+y^3=y^9
and x-y^9=-y^3
