To do this, we must allow this hidden number to be x.
2x + 4 = 8
Now we will solve by first subtracting 4 from each side:
2x = 4
Now we will divide each side by 2 to isolate the variable:
x = 2
Therefore, the mystery number is 2.
The answer is D! good luck
I think
V = l w h <span>V = s3</span>
V = (5 mm)(5 mm)(5 mm) V = (5 mm)3
<span>V = 125 mm3</span> <span>V = 125 mm<span>3</span></span>
Answer: The area of the triangle is: " 2v⁴u² square units" ;
or, write as: " 2v⁴u² units² " .
______________________________________________________
<u>Note</u>: The formula/equation for the area, "A", of a triangle is:
A = (1/2) * b * h ; or: A = (b * h) / 2 ;
______________________________________________________
in which: "A" = "area" ;
"b" = "base length" ;
"h" = "[perpendicular] height" ;
______________________________________________________
We are asked to solve for the area, "A" .
We are given: "b = 4v³ " ; "h = vu² " ;
So; to find the area, "A", of the triangle, we plug these given values into the formula; and solve/ simplify:
____________________________________________________
A = (1/2) * b * h ;
A = (1/2) * (4v³) * (vu²) ;
A = 2v³ * vu² ;
A = 2v⁴u² square units.
Answer: The area of the triangle is: " 2v⁴u² square units" ;
or, write as: " 2v⁴u² units² " .

If a vertical line is drawn then the line will cut at only one point. In first graph for all x values we have different y values so the ordered pairs represent a function.
