Answer: Length = 28cm
Width = 7cm
Step-by-step explanation:
Let the width be represented by x.
Since the length is four times its width. Therefore, the length would be:
= 4 × x = 4x
The perimeter of a rectangle is calculated as:
= 2(length + breadth)
Therefore, 2(4x + x) = 70
2(5x) = 70
10x = 70
x = 70/10
x = 7
Therefore, width = 7cm
Length = 4x = 4 × 7 = 28cm
Y = 2, so C. Have a good day :)
Answer:
1. 9 to the power of 7
2. 7 to the power of 8
3. 10 to the power of 8.
4. 3 to the power of 9.
5. 2 to the power of 12.
Step-by-step explanation:
The associative property never works with subtraction.
For example:
2 - (7-8) <span>≠ (2-7) - 8
2-(-1)=3, but (-5)-8=-13
</span>
