Answer:
f(x)=x(x-5)(x+2)
Step-by-step explanation:
Since the steps of the factorization of the polynomial f(x) is not given, I will proceed to give the correct factorization of f(x).
f(x)=x³-3x²-10x
First, we factor out x since it is a common term.
f(x)=x(x²-3x-10)
Next, we factorize the quadratic expression x²-3x-10.
f(x)=x(x²-5x+2x-10)
f(x)=x(x(x-5)+2(x-5))
f(x)=x(x-5)(x+2)
The correct factorization of the polynomial f(x)=x³-3x²-10x is: f(x)=x(x-5)(x+2)
Answer:
X = 1h15mins
Step-by-step explanation:
Rate Time Distance
Morgan 20 X 20X
Corona 25 X – ¼ 25(X – ¼)
If they meet each other, they need to travle the same distance, mean :
20X = 25(X – ¼)
X = 1.25
1 hour and 15 minutes
Answer:
B , C and d are true because thsimilarey are
Answer:
C.
Step-by-step explanation:
5/4x-2=3/2x-4
5/4x-3/2x = -4+2
(multiply both sides by 4)
5x-6x=-16+8
-x=-8
(multiply by -1)
x=8
Answer:
D.72cm²
Step-by-step explanation:
sa=5(s²)+(s×w)+(L×s)+(s×p)
sa=5(3²)+(3×6)+(2×3)+(3×1)
sa=45cm²+8cm²+6cm²+3cm²
sa=72cm²
