4x(3-y) - 2x + xy
I got 64.
Is that right?
I forgot to put that x=4 and y=-2
4x(3-y) - 2x + xy
16 - 32 - 8 - 8 = - 32
Where did I go wrong?
I did this:
16(3--2) -8 + -8
16(5) + -16
80-16= 64
Thanks for your help.
16(3--2) -8 + -8
You forgot to multiply 16 * -2.
I see that now! Thank you!
To check if your answer of 64 is correct, we can simplify the expression step by step.
Given expression: 4x(3-y) - 2x + xy
1. Distribute 4x to both terms inside the parentheses:
⇒ 12x - 4xy - 2x + xy
2. Combine like terms (terms with the same variable and exponent):
⇒ (12x - 2x) + (-4xy + xy)
⇒ 10x - 3xy
So the simplified expression is 10x - 3xy.
Now, to determine if your answer of 64 is correct, we need to know the values of x and y. Please provide the values of x and y so we can calculate the expression.
