Perimeter of a rectangle. "find the value of x"
.
systems of equations and inequalities. last question.

x = 3

Step-by-step explanation:

Perimeter of the rectangle = 2(l + b)

where l is the length of the rectangle and

b is the breadth of the rectangle.

Here, the perimeter is given to be 18 meters.

And l = 2x m and b = x m

⇒ 18 = 2(2x + x) = 2(3x) = 6x

⇒  x = 3

∴ The value of x is 3 m.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
