Answer:
A=9
B=3
C=3
Step-by-step explanation:
5×9=45
3×3=9
Answer Picture:
200
7 times 5
35
divided by two
17.5
times 3
52.5 cubic inch
⇒ The given quadratic equation is x2−kx+9=0, comparing it with ax2+bx+c=0
∴ We get, a=1b=−k,c=9
⇒ It is given that roots are real and distinct.
∴ b2−4ac>0
⇒ (−k)2−4(1)(9)>0
⇒ k2−36>0
⇒ k2>36
⇒ k>6 or k<−6
∴ We can see values of k given in question are correct.
