Combine like terms.
12x^4 + 4x^3 - x^2
In a 45 · 45 · 90 triangle, the hypotenuse is √2 · legs, because a 45 · 45 · 90 triangle is isosceles, so the legs are the same length. So, we have 3√2 · √2 = 6, so the hypotenuse is 6.
x=6
The mixed number is a fraction so the question is not able to be solved.
Hope this helps.
The square root of 144x^2 = 12 x
and square root of + 81 = 9 or -9
if this polynomial were a perfect square then its factors would be
(12x - 9)(12x - 9)
but its not a perfect squre because (12x - 9)(12x - 9) = 144x^2 - 216x + 81.
Answer:
68
Step-by-step explanation:
8 + 3 (71 – 51)
71-51= 20
20*3=60
60+8=68
