Answer:
I think system 4 has no solution
Step-by-step explanation:
I'm sorry if you get it wrong
11) A rectangle = 11.5 x 9.5 = 109.25
A triangle = 8x 9.5 = 38
Total area = 109.25 + 38 = 147.25
Answer: C
all shapes must equal 360 degrees
90 x the 4 angles of the square equals 360 degrees
X+8y=18
-5x+3y=-4
Multiply the first equation by 5
Add the two equations together
5x+40y=90
-5x+3y=-4
43y=86
Y=2
Plug y into one equation to find x
X+16=18
X=2
