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

What is the LCM of 40 and 70 with solution?

Least Common Multiple (LCM) for 40 70 is 280The Least Common Multiple (LCM) is the smallest number that two or more numbers will divide into evenly. NOTE: to find LCM you first need to know how to find GCD/GCF.Step 1: Find the GCF (Greatest Common Factor ) of 40 and 70 which is 10Step 2: Multiply the numbers 40 and 70 together ( 40 * 70 = 2800 )Step 3: Divide the 2800 with 10. (2800/10 = 280)So, the LCM of 40 and 70 is 280


What is the lcd of 40 and 18?

The simplest way to go about this, so you know you did not make a mistake is make a factor tree to find the LCM of both 40 and 18 so for 40 8-----5 4---2 2--2 LCM = 5*2*2*2 for 18 6----3 3---2 LCM = 3*3*2 LCM for 40 and 18 = 5*2*2*2*3*3=360 LCM would equal the LCD if you were using this to find lowest common denominator! LCD=360 so for 40 you would have to mulptiply 9 times and for 18 multiply 20 times! Hope this helps!
