The answer to question 1 is here, I don't understand question 2 so I can't answer it.
"the difference of a number x and 4": x - 4
"is": =
"3": 3
Combine the terms so that it looks like the sentence numerically:
"the difference of a number x and 4 is 3": x - 3 = 4
x - 3 = 4 is your answer.
To solve for x:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Add 3 to both sides.
x - 3 = 4
x -3 (-3) = 4 (-3)
x = 4 - 3
x = 1
1 is your answer for x.

Answer:
610m^2
Step-by-step explanation:
first we find the total area:
25*42=1050
then, we find the area of the white rectangle:
20*22=440
to find the area of the shaded region (which i'm assuming is the blue part), we can subtract the total area by the area of the white rectangle:
1050-440=610
so, the total area is 610m^2.
If it is stationary it is possible to go eastward if its by a wall and it would hit at about 4 m/s
Eastward 4m/s
