Answee:
We have these two equations:
-2x +4y =-22
2x + 8y -26
We need to try to get the same number multiplying both x or y, I think we can make the 2 of the first equation negative, for that, we multiply all the equation by -1:
2x + 8y =-26 ---- -2x - 8y =26
Now we have this:
-2x +4y = -22
-2x -8y = 26
Now e substract both equations:
-2x - (-2x) +4y -(-8y) = -22-26
12y = -48
Y = -48/12 = -4
And we replace to get x
-2x + 4y = -22
-2x +4*(-4)=-22
-2x - 16 = -22
x= -6/-2 =3
Answer:
It’s a obtuse triangle/scalene triangle
Step-by-step explanation:
Giving the information that is provided if the sides are not equal then it seems to be that the correct answer would be Obtuse Scalene
The answer would be 30.
60/2 = 30
90/2 = 45
120/2 = 60
Answer:

226.2 is the answer.
Answer:
x=10 and x=-9
Step-by-step explanation:
Factor:
(x-10)(x+9)=0
x-10=0
x=10
and
x+9=0
x=-9
