Step-by-step explanation:
the area of the square is (x+2)^2 and the factored form of it is x^2+4x+4
since we know the area is = 7 therefore
x^2 + 4x +4 = 7 and x^2 + 4x = 3
if you want to find the value of x :
x^2+4x+4 = 7
x^2+4x -3 = 0
(x-3)(x-1)=0
x = 3 or
x = 1
I got −15,045,083.2130533
Answer:
The equation for a line that is parallel to y + 5 = 3(x - 1) and goes through the point (3,-4) will be:
Step-by-step explanation:
Given the equation
y + 5 = 3(x - 1)
Writing in the slope-intercept form
y=mx+b
where m is the slope and b is the y-intercept
y = 3(x-1) -5
y = 3x-3-5
y = 3x - 8
Thus, the slope = m = 3
We know that the parallel lines have equal slopes.
So, the slope of a parallel line is also 3
Using the point-slope form of the line equation

substituting the values m = 3 and the point (3, -4)
y-(-4)=3(x-3)
y+4 = 3x-9
y = 3x-9-4
y = 3x-13
Thus, the equation for a line that is parallel to y + 5 = 3(x - 1) and goes through the point (3,-4) will be:

Answer:
x=17
Step-by-step explanation:
Since these angles are supplementary, they will add up to 180 degrees, so you can set up the equation like this:
4x+8+104=180
First, combine like terms:
4x+(8+104)=180
4x+112=180
Next, subtract 112 from both sides:
4x+112(-112)=180(-112)
4x=68
Then, divide each side by 4:
4x(/4)=68(/4)
x=17
17 is your answer.
