Hello there. I need some algebraic Help! What is 4x(2x - 9)
There are 4 potential answers to the question
A. 8x - 36x
B. -x
C. 28x^2
D. 8x^2 - 36x
:)
It is D, 8x^2 - 36x
Thank you very much!
To simplify the expression 4x(2x - 9), we need to distribute the 4x to both terms inside the parentheses.
The distributive property states that a(b + c) = ab + ac.
So applying the distributive property to our expression, we get:
4x * 2x - 4x * 9
Simplifying further:
8x^2 - 36x
Therefore, the correct answer is D. 8x^2 - 36x.
Hello! I'd be happy to help you with your algebra question!
To expand the expression 4x(2x - 9), you need to distribute the 4x to both terms inside the parentheses. This means multiplying 4x by 2x and then by -9. Let's go step by step:
Step 1: Multiply 4x by 2x:
4x * 2x = 8x^2
Step 2: Multiply 4x by -9:
4x * -9 = -36x
Combining these two results, the expanded expression becomes:
8x^2 - 36x.
So, the correct answer is D. 8x^2 - 36x.
