8. Find the value of x so that line mis parallel to line l. (1 p<br><br> (3x+21)°<br><br> (4x-7)

dybincka [34]

Answer: The value of x is 28.

Step-by-step explanation:

Since line m is parallel to line l.

So, we assume that

(3x+21)° and (4x-7)° are corresponding angles.

And we know that , corresponding angles formed when a transversal cut the parallel line are equal.

So, they must be equal to each other.

$3x+21=4x-7\\\\21+7=4x-3x\\\\28^\circ=x$

Hence, the value of x is 28.

Rewrite each expression as a polynomial in standard form: (2x^2 − x^3 − 9x +1) − (x^3 +7x − 3x^2 +1)

Vitek1552 [10]

Answer:

Polynomial in standard form will be $-2x^3+5x^2-16x$

Step-by-step explanation:

We have given polynomial $2x^2-x^3-9x+1-(x^3+7x-3x^2+1)$

We have to write this polynomial in standard form

For writing in standard form we have to first subtract the polynomial and then rearrange the order

So $2x^2-x^3-9x+1-(x^3+7x-3x^2+1)=2x^2-x^3-9x+1-x^3-7x+3x^2-1=-2x^3+5x^2-16x$

So polynomial in standard form will be $-2x^3+5x^2-16x$
