Answer:x^3+13x^2+3
Step-by-step explanation:
(2x^3+11x^2+5)-(x^3-2x^2+2)
Clearing brackets
2x^3+11x^2+5-x^3+2x^2-2
Collect like terms
2x^3-x^3+11x^2+2x^2+5-2
x^3+13x^2+3
Yes in order for them to be symmetrical they both have to be Symmetrical or the same
Answer:
6.8
Step-by-step explanation:
a^2 + b^2 = c^2
6.6^2 + b^2 = 9.5^2
43.56 + b^2 = 90.25
b^2 = 90.25 - 43.56
b^2 = 46.69
(take square root of both sides)
b = 6.8
