THE AREA IS 78
Cause 13 x 12 is 156 and 156 divid by 2 is 78
Answer:
first piece = 5 m
second piece = 2(5) + 2 = 12 m
third piece = 3(2x + 2) = 6(5) + 6 = 36 m
Step-by-step explanation:
The question is incomplete, the length of the actual rope is unknown but it should be given . Let us assume the length of the rope is 53 meters.
The rope is cut into 3 pieces of different length.
first piece = x
second piece = 2x + 2
third piece = 3(2x + 2) = 6x + 6
Since the length of the actual rope is assumed to be 53 meters .The length of the first piece, second piece and third piece can be calculated as follows.
we add the length of the pieces to get the actual length of each piece. Therefore,
x + 2x + 2 + 6x + 6 = 53
collect like terms
9x + 8 = 53
9x = 53 - 8
9x = 45
x = 45/9
x = 5 meters
first piece = 5 m
second piece = 2(5) + 2 = 12 m
third piece = 3(2x + 2) = 6(5) + 6 = 36 m
Answer:
y + 8 ≤ 17
Step-by-step explanation:
"The sum" means to add.
"The sum of 8 and y" = y + 8
"less than or equal to" = ≤
"17" = 17
Set the equation:
y + 8 ≤ 17 is your answer.
~
Use the formula y2-y1/x2-x1 and sub in the points
