Use distributive property and combining like terms. I'M BEGGING YOU PLEASE HELP ME!!!!
9(nn-1)+7n
3+5(-n+2)
4(2n+3)-6n+5
Someone, please help me
Yall I need help please
first, check for typos
next, review the distributive property
I'll do the first one; you try the others
9(n-1)+7n
9n - 9 + 7n
16n - 9
I can definitely help you with these expressions! Let's break them down one by one using the distributive property and combining like terms.
Expression 1: 9(nn-1)+7n
To solve this expression, we will use the distributive property. The distributive property states that you can distribute a number to each term inside parentheses. In this case, we have nn and -1 inside the parentheses.
9(nn-1) can be simplified as 9 * nn + 9 * (-1). When multiplying nn by 9, we get 9nn. When multiplying -1 by 9, we get -9.
Now, combining like terms means combining similar terms together. In this expression, the only like terms are 9nn and 7n. They have the same variable (n), so we can group them together.
Putting it all together, the expression simplifies to 9nn-9+7n.
Expression 2: 3+5(-n+2)
Again, using the distributive property, we multiply 5 by -n and 5 by 2.
5(-n+2) simplifies to -5n + 10.
Now, we combine the like terms. The expression becomes 3 + (-5n) + 10.
Simplifying, we have -5n + 13.
Expression 3: 4(2n+3)-6n+5
First, we use the distributive property to multiply 4 by 2n and 4 by 3.
4(2n+3) simplifies to 8n + 12.
Now, we combine the like terms. We have 8n - 6n + 12 + 5.
Combining 8n and -6n gives us 2n. Combining 12 and 5 gives us 17.
So, the final simplified expression is 2n + 17.
Remember, the key steps to solve these expressions are applying the distributive property and then combining like terms.
