3. There is a missing digit.
Step-by-step explanation:
Given: <u>y=3</u> and <u>x= 1/2</u>
<h2>Question 1: 4(2y-4x)-1=</h2>- Numerical factors in this term have been multiplied.
4(6-4/2)-1
- We can reduce this fraction by dividing both numerator and denominator by a common numeric factors.
4(6-2)-1
- Numerical terms in this expression have been added.
4*4-1
- Numerical factors in this term have been multiplied.
16-1
- Numerical terms in this expression have been added.
15
<h2>Question 2: 4x^2+2y^3-10 = </h2>4/2²2*27-10
4/2²+54-10
- We need to perform a multiplication.
- The following rule is applied:
45: Numerical factors in this term have been multiplied.

Option C: is the possible expressions for length, width and height of the prism.
Explanation:
The volume of the rectangular prism is
To determine the length, width and height of the rectangular prism, let us factor the expression.
Thus, factoring 5x from the expression, we have,
Let us break the expression into two groups, we get,
Factoring 4x from the term , we get,
Similarly, factoring 7x from the term , we get,
Now, let us factor out , we get,
Hence, the possible expressions for length, width and height of the prism is
Therefore, Option C is the correct answer.
