Suppose you were trying to multiply 17 x 5 x 2. The associative property states that (17 x 5) x 2 = 17 x (5 x 2) The second one is easier to do in your head.

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

How can associative property of multiplication can help solve math problems mentally?

You can do the easy bits first. Thus, to calculate 7*5*2, instead of doing 35*2 = 70, you can calculate 7*10 = 70. By itself, the associative property is not as useful as it is in combination with the commutative and distributive properties.

How did finding the factors with two numbers help you find ways to multiply with more than two numbers?

Using the commutative and associative properties of multiplication it is sometimes possible to simply the multiplication.For example, to multiply 35 by 6,35 = 5*76 = 2*3therefore, 35*6 = (5*7)*(2*3) use the associative property= 5*7*2*3 use the commutative property for the middle two terms= 5*2*7*3 use the associative property for the first two terms, and for the other two terms.= (5*2)*(7*3) = 10*21 = 210.

How do the commutative and associative properties of multiplication could help evaluate the product of 5 multiplied by 17 multiplied by 2 mentally?

5*2 is 10 and 10*17 is 170

How do commutative and associative properties help solve 5x17x2?

5*17*2 The commutative property allows yu to swap the 17 and 2: = 5*2*17 The associative property allows you to group 5 and 2 to evaluate first = (5*2)*17 = 10*17 = 170

Which property would help you solve 42 15 28 mentally because you would add 42 and 28 first then add 15?

the property says that a+b+c is the same as a+c+b and it is the commutative property of addition.

How you can make 10 to help you add 4 9?

4 = 3 + 1 so 4 + 9 = (3 + 1) + 9 Then, by the associative property, = 3 + (1 + 9) = 3 + 10 = 13

How can knowing the multiplication properties help you evaluate 5 times 20 times 63?

According to the associative property when more than two numbers are multiplied, the order in which the numbers are multiplied will give the same product.

How does associative property of multiplication help to calculate products mentally?

For example, evaluate 17*5*20: Method 1: (17*5)*20 = 85*20 = 1,700. Method 2: 17*(5*20) = 17*100 = 1,700. Notice that by first multiplying 5*20 to get 100, the calculation is easy to do in your head. You can also use the commutative property to rearrange a question: 5*21*4 = 5*4*21 = 20*21 = 420
