Answer:
Length = 22cm
Step-by-step explanation:
Perimeter of a rectangle, P = 2(L + W)
Also, from the question, P = 80 cm
Therefore, P = 2(L +W) = 80
The length is 4 cm longer than the width
then, length, L = 4 + W
Slot in the value of L
2 {(4+W) + W} = 80
2(4 + 2W) = 80
8 + 4W = 80
Subtract 8 from both sides
8 - 8 +4W = 80 -8
4W = 72
Divide both sides by the coefficient of W which is 4
W = 18 cm
Recall,
L = 4 + W
L = 4 + 18
L = 22cm
Answer:
Step-by-step explanation:
The number is divisible by 4 if the number formed by the last two digits is divisible by 4.
Since we are looking for the largest possible option, lets try 2-digit numbers formed by the given digits.
The smallest 2-digit number that is divisible by 4 is 36
<u>Then the largest number is:</u>
3/6 = 6/x+3
3x + 9 = 36
3x = 27
x = 9
400Million meteres tall
scientific notation: 4×10^8
Answer:
x = 0.5
