The answer is -110.
This is because -55-55=-110.
You have to put -55-55 because the question is asking for you to multiply -55 twice, which is technically-55-55.
Here is what you have to do first, combine like terms. On the left side do x-3x (you can do 1x-3x because x is just 1 variable, so I can see why you put 1x instead of x). Then combine -3-1. Then add the x answer on the left side to the 2x on the other side then you can figure out the rest. The reason why I want you to figure out the rest is because I'm just helping you and you need to get the answer yourself.
Answer: x>-1
Step-by-step explanation:
Dotted line on the axis is covering y infinitely, so theres an inequality on x, and the line is at -1, so x should be > - 1
Answer:
x = 6 cm
Step-by-step explanation:
The area is the product of length (x +2) and width (2x -5). It is 56 cm², so for all dimensions in cm, we can write ...
(x +2)(2x -5) = 56
2x² -x -66 = 0 . . . . . subtract 56 to put into standard form
(x -6)(2x +11) = 0 . . . . factor
Solutions to the equation are values of x that make the factors zero:
x = 6, x = -11/2
The negative solution is extraneous, so the solution of interest is ...
x = 6 cm
