6. Expand the expression 4(x + 5).
PLEASE HELP DUE TOMORROW

4x+20

Step-by-step explanation:

Using the distributive property you multiply the terms outside by the terms inside. So the expression will be like this

4(x)+4(5)

When simplified the answer is

4x+20

this might be little bit diffult but hope it helps :)

Step-by-step explanation:

the equation of a parabola in vertex form is

Y = a(x−h)2+k

Where the (h,k)  are the coordinates of the vertex and is a multiplier

Here (h,k) = (0,0) thus

Y = ax2

to find a subsitiude (-1, -4) into a equation

-4 = A

So y = -4x 2

So take this infomation and put it into the (0,0) and (20,15)

Hope this helps :) let me know if this isnt right
