Answer:
24.36m²
Step-by-step explanation:
area = ½×(8.9+2.7)×4.2= ½×48.72=24.36m²
Answer:
2.67 and 4.67 I think .........
Your answer would be approximately 254.5 if you round since 9^2 times pie you would get such
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
