Step-by-step explanation:
y=2(x+3)² y=x²
x²=2(x²+9+6x)
x²=2x²+18+12x
0=x²+18+12x
x²+18+12x=0
Answer:
Square Root of 162 ~ 12.727
Step-by-step explanation:
Simply do the Pythagorean Theorem!
a^2 + b^2 = c^2
This case we're solving for the long side which is the hypothenuse.
9^2+9^2= c^
81+81=c^
162=c^
Square root of 162
Which is 12.727
