Please help me -x + 2 = 4
find x
is that even posabull the bigist number I can find is 3
By the way x is negitv

-x = 4 - 2

-x = 2

x = -2

Explanation:

To find variable x we need to move positive 2 to right hand side which will become negative 2 and when 4 is substrated from 2 we get positive 2 and to make variable x positive we need to take negative sign to right hand side.

u need to make the postive 2 a negitive.

Step-by-step explanation:

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
