Area of hexagon = base * (apothem/2) * 6 = 3(base*apothem)
=3*15*20
=900 square units.
However, a hexagon consists of 6 equilateral triangles in which the apothem is 0.866 times the base, meaning that the apothem is shorter than the base.
Perhaps the base is 20 and apothem 15. The answer will come to be the same though.
Answer:
Well elimination is basically multiplying a number to make it possible for it to cancel out
We can multiply the first equation by 2
2(x+2y=-1)
This would be
2x+4y=-2
Its still the same thing but just with non simplified numbers
We can now do any method really to solve
I will just do the subtraction method
2x+4y=-2
-2x+y=4
Solve
2x-2x=0
4y-y= 3y
-2-4= -6
3y= -6
Now solve
y=-2
To find x subsitute in “y” and find ”x”.
x+2*-2=-1
x-4=-1
x=3
y= -2
x= 3
It'll go positive but for every number or goes half way
Answer:
B
Step-by-step explanation:
Given the 2 equations
3x - 2y = 6 → (1)
5x + 4y = 32 → (2)
Multiplying (1) by 2 and adding to (2) will eliminate the y- term
6x - 4y = 12 → (3)
Add (2) and (3) term by term to eliminate y
11x = 44 ( divide both sides by 11 )
x = 4
Substitute x = 4 into either of the 2 equations and solve for y
Substituting into (2)
5(4) + 4y = 32
20 + 4y = 32 ( subtract 20 from both sides )
4y = 12 ( divide both sides by 4 )
y = 3
Solution is (4, 3 ) → B
