Step-by-step explanation:
Given expression is x⁴-kx²+4 =0
x−2 is a factor of the given expression.
So, x=2
Substitute in the equation, we get
2⁴-k(2)²+4
⇒16+4k+4=0
⇒4k=−20
⇒k=−5
Answer:
-170.6666667
Step-by-step explanation:
hope this helps
2x+x=180
3x=180
X=60
And other angle is 120
20*5= 100
375+100=475
475/5= 95
Therefore the original price of a sweater is $95
