{ \tt{3x -  {2x}^{2}  + 4 -  {x}^{2} + x }} \\

» Collect second degree terms (x² coefficients) together and first degree terms (x coefficients) and constants

= { \tt{( - 2 - 1) {x}^{2} + (3 + 1)x + 4 }} \\  = { \boxed{ \tt{ \:  -  {3x}^{2}  + 4x + 4}}}

-3x + 4 = -29<br> what does x= ?
Crank

Answer:

x = 11

Step-by-step explanation:

-3x + 4 = -29

step one : subtract 4 from both sides

-3x = -29 - 4

-3x=-33

step two : divide -3 from both sides

-33 ÷ -3 = 11

x = 11

check your work now

-3(11) + 4 = -29

-3 x 11 = -33

-33 + 4 = -29

Evaluate the following expression. (-3)-2
harkovskaia [24]
Integers are whole numbers that are either positive or negative. Operation of signs is important when dealing with integers.
In this case, -3 and -2 are integers that are being added.
if we add -3 by -2 we get -6 because when a negative number is added to a negative number the negative sign does not change
thus, (-3)-2 = -5
