Answer:
x=-4
Step-by-step explanation:
Answer:
Perimeter = 24 + 8π /3 m.
Step-by-step explanation:
Arc length = rC where r = radius and C = angle in radians.
40 degrees = 40 π / 180
= 2π /9 radians.
Arc length = 12 * 2π /9
= 8π /3 m.
Perimeter of the sector = 2*12 + 8π /3
= 24 + 8π /3 m.
Solve for X and y using both equations the point you get will be the point they cross eachother
-x-y=1
y=x+3
-x-(x+3)=1
-x-x-3=1
-2x-3=1
+3 both sides
-2x=4
÷-2 both sides
x=-2
solve for y
y=-2+3
y=1
(-2,1)
First use PEMDAS so 26x2=52
52-3=49
4+49=53
53x4
