9a-4(2a+5). i really need with this question

First you had to expanded form.

Finally you can also add by similar to elements.

Final

Hope this helps!

And thank you for posting your question at here on , and have a great day.

hope i'm right lol

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
