2 answers:
If you simplify (x-3)(x^2-4x-7)
answer: x^3-7x^2+5x+21
Answer:
Simplification of the expression (x−3)( x^2−4x−7) is x³ -7x² + 5x + 21 .
Step-by-step explanation:
As the expression given in the question be as follow .
= (x−3)( x²−4x−7)
simplify the above
= x (x²-4x-7)-3 (x²-4x-7)
Now open the bracket
= x³ - 4x² -7x - 3x² + 12x + 21
= x³- 4x²-3x²-7x + 12x + 21
= x³ -7x² + 5x + 21
Thus the simplification of the expression (x−3)( x^2−4x−7) is x³ -7x² + 5x + 21 .

Answer:
16.6
Step-by-step explanation:
a = 14
b = 9
c = x
a² + b² = c²
14² + 9² = x²
196 + 81 = x²
x² = 277
x = 16.6
