Ok, so if a train travels 525 km in 4.7 hours, then
525/4.7 is 111.702128,
so therefore 111.702128 miles/hr.
To check, 111.702128 multiplied by 4.7 is 525.000002, so close enough.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials
