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.
Answer:

➳ These equations will have <u>infinite solutions</u> because they are in 2 variables. Any value can be substituted in the place of the variables x & y.
Answer:
X= - 44
18x+3x+4-5=5(4x9
Collect like terms
21x+4-5=5(4x-9
More variable to the left hand side and change its sign
21x-20x-1=-45
Correct like terms
X=-45+1
Which is x=-44
Answer:
f = 16
Step-by-step explanation:
2 = f/8
Cross Multiplying, we get
f = 16
