Answer:
Correct to 1dp
127.3 cm = 127.0 cm
86.5 cm = 87.0 cm
Upper limits:
127.0 cm = 127.05 cm
87.0 cm = 87.05 cm
Lower Limits:
127.0 cm = 126.95 cm
87.0 cm = 86.95 cm
upper limit of perimeter of rectangle:
P = 2(l+w)
= 2(127.05 + 87.05)
= 2(214.1)
= 428.2 cm
lower limit of perimeter of rectangle:
P = 2(l+w)
= 2(126.95 + 86.95)
= 2(213.9)
= 427.8 cm
therefore;
Hello!
We know that
(x - 10) * 3 = 2x
Distribute the 3
3x - 30 = 2x
Subtract 2x from both sides
x - 30 = 0
Add 30 to both sides
x = 30
The answer is 30
Hope this helps!

Answer: Perimeter = (4x + 40) feet
Step-by-step explanation:
Given that the
Length of the garden = 15 feet
And
Width of the garden = 5 feet
The length and the width of the garden increase by an equal value.
To find the expression representing the perimeter of the garden,
Let x be the increased amount of length.
Thus, the new length of garden becomes (x+15) and the new width of garden becomes (x+5)
Let us assume that the garden is a rectangle, then,
Perimeter of garden = 2(L + W)
= 2(x + 15 + x + 5)
= 2(2x + 20)
= (4x + 40) feet.
Or
Perimeter = (x+15) + ( x + 5 ) ( x + 15 ) + (x + 5 )
= 4x + 40
