-) 2x(4+4-49-1-2)x2 =

-88x^3

Step-by-step explanation:

1) distribute the "2x"

(8x+8x-98x-2x-4x)x^2

a) add all like terms in parantheses

(-88x)x^2

b) multiply -88x and x^2

-88x*x^2=-88x^3

hope this helps!

step-by-step explanation:

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
