Answer:
see below
Step-by-step explanation:
2x+8y=12 3x-8y=11
If we have to solve by substitution, Take the first equation and divide by 2
2x/2 + 8y/2 =12/2
x+4y = 6
Then subtract 4y from each side
x = 6 -4y
Then substitute this into the second equation
This is best solved by elimination
2x+8y=12
3x-8y=11
----------------
5x = 36
x = 36/5
Center is ( -1.6 , -9.8 , 0 )
radius = √26 = 5.099 = 5.1
Answer:

B and.

Answer:
x=4²-((3×2)÷2)
x=13
Step-by-step explanation:
assuming this is a right triangle (90dgr)
area of the square... a×a
area of the right triangle..= (width×height) ÷2
