Can you help my brother I rlly don’t wanna help him

I think it is 23

Step-by-step explanation: i think this becasethe operation performed on numbers, available in brackets that can be distributed for each number outside the bracket. It is one of the most frequently used properties in Maths. The other two major properties are commutative and associative property.

The distributive property is easy to remember. There are a number of properties in Maths which will help us to simplify not only arithmetical calculations but also the algebraic expressions.  In this article, you will learn what is distributive property, formula, and solved examples.

Distributive Property Definition

The Distributive Property is an algebraic property that is used to multiply a single value and two or more values within a set of parenthesis. The distributive Property States that when a factor is multiplied by the sum/addition of two terms, it is essential to multiply each of the two numbers by the factor, and finally perform the addition operation. This property can be stated symbolically as:

A ( B+ C) = AB + AC

Where A, B and C are three different values.

Let’s consider a simple example: 2(4 + 3).

Since the binomial “4 + 3” is in the parenthesis, according to the order of operations, you have to calculate the value of 4 + 3 and then multiply it by 2, which gives the resultant value as 14.

Part A: The test average for the math class after completing test 2 is 81

Part B: The test average for the science class after the completing test 2 is 83

Part C: The science class had a higher average after completing test 4

Step-by-step explanation:

f(x) = 0.5x + 80 represents the average test score in your math class, where x is the number of the test taken

g(x) represents the average test score in your science class, where x is the number of the test taken

Part A:

f(x) = 0.5x + 80

f(2) = 0.5 * 2 + 80

f(2) = 81

Part B:

g(x) = 2x + 79

g(2) = 2 * 2 + 79

g(2) = 83

Part C:

f(4) = 0.5 * 4 + 80

f(4) = 82

g(4) = 2 * 4 + 79

g(4) = 87
