No, she is not correct.
A "composite" is a number that can be divided evenly (no decimals) by something other than itself (43) and 1.
43 has no other numbers that can divide into it and leave it a whole number.
You multiply using the multiplication table. Multiplication is one of the four basic operations in arithmetic, along with addition, subtraction, and division. Multiplication can actually be considered repeated addition, and you can solve simple multiplication problems by adding repeatedly. For larger numbers, you'll want to do long multiplication, which breaks the process down into repeated simple multiplication and addition problems. You can also try a shortcut version of long multiplication by splitting the smaller number in the problem into tens and ones, but this works best when the smaller number is between 10 and 19.
Answer: OPTION C.
Step-by-step explanation:
The missing options are:

In order to solve this exercise you need to remember the following:
1. The Distributive property states that:

2. The multiplication of signs:

In this case the exercise gives you the following equation:

Since you need to solve for the variable "x" in order to find its value, the first step you must apply in the in the procedure is to eliminate the parentheses applying the Distributive property.
Then, you must multiply everyting inside the parentheses by
.
Therefore,based on the explanation, you know that the correct use of the Distributive property is:

Do sqrt(18^2)+26^2)). It should give you the answer.
