when simplifying the expression 9(21x+x)^2-18x what is the coefficent of x after the first step
wrong
-18 is wrong
Apologies for the mistake. Let's correct it:
The given expression is 9(21x + x)^2 - 18x.
Within the parentheses, we simplify:
21x + x = 22x
Substituting this back into the expression:
9(22x)^2 - 18x
Now, let's square 22x:
(22x)^2 = 484x^2
Substituting back into the expression, we have:
9 * 484x^2 - 18x
So, after the first step, the coefficient of x is -18.
when simplifying the expression 9(21x+5x)^2-18x what is the coefficent of x after the first step
To simplify the expression 9(21x + 5x)^2 - 18x, we need to perform the operations inside the parentheses first. Simplifying the expression inside the parentheses, we have:
21x + 5x = 26x
Substituting this back into the original expression, we get:
9(26x)^2 - 18x
Now, we square 26x:
(26x)^2 = 676x^2
Now, substituting back into the expression, we have:
9 * 676x^2 - 18x
So, after the first step, the coefficient of x is -18.
still wrong change your answer smh
Apologies for the incorrect response. Let's correct it:
The expression is 9(21x + 5x)^2 - 18x.
Within the parentheses, we simplify:
21x + 5x = 26x
Substituting this back into the expression:
9(26x)^2 - 18x
Now, we square 26x:
(26x)^2 = 676x^2
Substituting back into the expression, we have:
9 * 676x^2 - 18x
So, after the first step, the coefficient of x is -18.
answer is 26
To simplify the expression 9(21x + x)^2 - 18x, we need to perform the operations inside the parentheses first. Simplifying the expression inside the parentheses, we have:
21x + x = 22x
Substituting this back into the original expression, we get:
9(22x)^2 - 18x
Now, we square 22x:
(22x)^2 = 22x * 22x = 484x^2
Now, substituting back into the expression, we have:
9 * 484x^2 - 18x
So, after the first step, the coefficient of x is -18.
Apologies for the mistake. Let's start again:
The given expression is 9(21x + x)^2 - 18x.
Within the parentheses, we simplify:
21x + x = 22x
Substituting this back into the expression:
9(22x)^2 - 18x
Now, let's square 22x:
(22x)^2 = 484x^2
