Answer 1

A polynomial having only one term is called monomial

Step-by-step explanation:

xyz  is not a  binomial

2x+9=5

=> 2x = - 4

=> x = - 2

x = - 2 is solution of 2x+9=5

Ajay's age after 7 years will be 18. His age 5 years ago was

=> current age = 18 - 7 = 11 Years

Age 5 years ago = 11 - 5 = 6 years

42= 7(5+x),

=> 6 = 5 + x

=> x = 1

The constant term in expression 2xyz + xy- 5z- 16 is   -16

p=3 and q= -3, find the value of 2p + q - 3pq. *

= 2(3) + (-3)   - 3(3)(-3)

= 6 - 3 + 27

= 30

Subtract (-23a) from 377a

=> 377a - (-23a)

= 377a + 23a

= 400a
