Please help. I've been asking about these questions for the past 1 and 30 min. I'm really confused
Simplify Please:
1: (-12xy2z)(3xy)
2: -12xy2z divided by 3xy
3: 2x(2x - 5)
4: -2x(2x-5)
You've been spamming the board and are about to be banned. Bob Pursley gave you and answer but you apparently don't understand it.
I don't know how to help you. You'll have to wait until another math tutor sees your posts and helps you. In the meantime, do not post this again.
I apologize. I'm having a rough day today. :( I'm so very sorry Ms. Sue. please forgive me.
Of course! I'll be glad to help you simplify these expressions. Let's go through each question step by step:
1: To simplify the expression (-12xy^2z)(3xy), we need to multiply the terms together. Start by multiplying the coefficients: -12 times 3 equals -36. Next, multiply the variables with the same base together using the property of exponents. In this case, we have x * x = x^2, y^2 * y = y^3, and z * 1 = z. Combining all these results, the simplified expression is -36x^3y^3z.
2: To divide -12xy^2z by 3xy, the first step is to divide the coefficients: -12 divided by 3 equals -4. Then, divide the variables with the same bases. In this case, we have x/x = 1, y^2/y = y^(2-1) = y, and z/1 = z. Therefore, the simplified expression is -4yz.
3: To simplify the expression 2x(2x - 5), we multiply the constant term 2x by each term inside the parentheses. This results in 2x * 2x = 4x^2 and 2x * -5 = -10x. Thus, the simplified expression is 4x^2 - 10x.
4: When simplifying -2x(2x-5), we need to distribute the -2x across the terms inside the parentheses. This means multiplying -2x by 2x and -5 individually. Doing so, we get -2x * 2x = -4x^2 and -2x * -5 = 10x. Therefore, the simplified expression is -4x^2 + 10x.
I hope these explanations clarify how to simplify these expressions for you! If you have any further questions, feel free to ask.
