Answer: Area = 88m²-----------------------------
I'm guessing you want to know how much is in one case,
36/3 = 12
To solve this system of linear equations we need a little trick called elimination steps are below
we are given the following system of equations
if you look at the x variables in both equations you can see that we can easily eliminate them by multiplying the bottom equation by -4 as so
simplify and we get
now we can combine like terms on each side with the x's cancelling and get
now divide off -35
great now we can go back to our original system and pick a equation and substitute y back in to find x lets use
so now we substitute y and get
now we put x and y into one coordinate (x,y)
so now our FINAL ANSWER IS
(-17,-1)
Answer:
x = 40
Step-by-step explanation:
Since FG and HI are parallel and BC is a transversal, then
∠ GBE and ∠ GBE are same side interior angles and are supplementary, thus
3x + 20 + x = 180, that is
4x + 20 = 180 ( subtract 20 from both sides )
4x = 160 ( divide both sides by 4 )
x = 40
According to the solving the perimeter of the given triangle is:
= -x³ + 13x² + 11x + 20
<h3>Describe the triangle:</h3>
Three edges and three vertices make up a triangle, which is a polygon. It is among the fundamental shapes in geometry. Triangle ABC refers to a triangle with the vertices A, B, and C. In Euclidean geometry, any three points that are not collinear determine a singular triangle and a singular plane at the same time.
<h3>What is the formula for the triangle's perimeter?</h3>
Simply summing the lengths of all the sides of a triangle yields its perimeter. A + B + C is the basic formula to determine the perimeter of a triangle with sides "a," "b," and "c."
<h3>According to the given data:</h3>
A = 9x+10x²-x³
B = -x² + 9x + 12
C = 4x²-7x+8
We know that the perimeter of the triangle is sum of all side of the triangle:
A+B+C
= (9x+10x²-x³) + (-x² + 9x + 12)+(4x²-7x+8)
= -x³ + 13x² + 11x + 20
