Ineed asap explain the error in the work and how you might prevent it. -14x  and 12x²  are not like terms, so they can’t be subtracted. to prevent this error, be sure to line up like terms.

Yes, there is an error because -14x and 12x² are not like terms, so they can’t be subtracted. To prevent this error, be sure to line up like terms.

Step-by-step explanation:

We need to check whether the given work is error free or not.

In the given problem is divided by .

In this case,

Using long division we get

So,

It the given work there is an error because -14x and 12x² are not like terms, so they can’t be subtracted. To prevent this error, be sure to line up like terms.

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
