Step-by-step explanation:
Let
Multiply x by a power of , one that keeps the decimal part of the number the same:
Subtract from
The repeating decimals should cancel out
solve for x
Divide by both sides
Answer:
while working on graphs there is an (X,Y) axis
#7 start at 0 then go right 2, up 4
#8 start at 0 then go left 6 then up 8
#9 start at 0 then go right 10 then down 12
#10 start at 0 then go left 14 then down 16
Step-by-step explanation:
Answer: 54 cm
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Perimeter of a square = side length x4
Replacing with the values given:
72 = 4 s
Solving for s (side length)
72/4=s
s = 18 cm
Since the side length of the square is the length of each rod, and all the rods have the same length, to obtain the perimeter of the triangle we have to apply:
Perimeter of an equilateral triangle: 3 side length
P = 3 (18 ) = 54 cm
