Answer:

B). The distributive property was not applied correctly in the second step.

Step-by-step explanation:

We need to find the correct option for marking error from given choices:

\left(x^2+2x+6\right)\left(2x^2-4x-1\right)

Step 1:

x^2\left(2x^2-4x-1\right)+2x\left(2x^2-4x-1\right)+6\left(2x^2-4x-1\right)

No error.

Step 2:

If you apply distributive property correctly then 2nd term gives:

2x\left(2x^2-4x-1\right)=4x^3-8x^2-2x

While 2nd term is not like that.

Hence final answer is :

B). The distributive property was not applied correctly in the second step.

What's <br> y=3x-3<br> 2y-x=4 as an ordered pair
matrenka [14]
I don’t wanna give the exact answer, i want to help you and lead you in the right place so you know the concept and process if a similar question is on an assessment. basically, the set of equations is set up for substitution method. we can agree that y equals 3x-3. so in the second equation, instead of writing “2y” you would SUBSTITUTE the y for 3x-3. so the equation would be 2(3x-3)-x=4. do the distributive property. once you get the equation after doing the distributive property, you solve for x using your algebra skills from previous units (cancel out x’s, for instance). your answer is your x coordinate. in order to find your y, you substitute whatever number you got for x and plug it in to one of the equations, doesn’t matter which. you will then solve for Y using your algebra skills you learned from previous units. after solving, you should get what y=. now you put the number in coordinate pair form which is (x,y)
