3(w+4)=3w+12 is an example of Distributive property

A distributive property usually conforms to a distributive law where each algebraic expression has an equal variable.

For example;

From the given expression

Others include:

An associative property refers to a rearrangement method used in algebraic terms in which the solution of the variables in the bracket is not affected in the algebraic expression.

i.e.

a+ (b+c) = (a+b) + c

A commutative property determines the multiplication or addition of variables by just altering their order without changing the result.

i.e.  

a + b = b + a

Distributive property

Step-by-step explanation:

The distributive property is where multiplying the sum of a group of numbers by another number will get you the same number as multiplying the numbers individually, then adding them together.

In this case, this means that adding w + 4 together, then multiplying it by 3, will get you the same number as 3w + 12, which is created by multiplying the numbers individually by 3, then adding them together.

So, this represents the distributive property.

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

207/8 is the right
