Question

Solve the following Problems : ​

Answer 1

Answer:

1 ) x³ - px + 10 x² - 6 = 0

=> 1³ - p×1 + 10 × 1 - 6 = 0 [ since, x =1 ]

=> 1 -p + 10 - 6 = 0

=> -p = -10 + 6 - 1

=> -p = -5

=> p = 5

ANS) the required value of p is 5

2) area of parallelogram = 18 cm²

height = 6 cm

base = ?

since, area = base × height sq cm

=> Base × 6 = 18 sq cm

=> base = 18÷6 cm

=> base = 3 cm

Ans) the required value of the base is 3 cm.
