Answer:
16 x units
Step-by-step explanation:
Perimeter of a original square= 8 x units
Perimeter of a square= 4× side
Side of a square =
Side of a square =
Side of a square= 2 x units
since four square are joined together to form a single square
So each side of a bigger square= 4 x units
Perimeter of a new bigger square= 4 × 4 x units
Perimeter of a new bigger square= 16 x units
Hence, the correct answer is 16 x units

What law is applied
The applied law is commutative law of addition.
This law states that:
So:
When the positions of 2 and b are interchanged, we have:
Remove bracket
Step-by-step explanation:
The simplest method is "brute force". Calculate each term and add them up.
∑ = 3(1) + 3(2) + 3(3) + 3(4) + 3(5)
∑ = 3 + 6 + 9 + 12 + 15
∑ = 45
∑ = (2×1)² + (2×2)² + (2×3)² + (2×4)²
∑ = 4 + 16 + 36 + 64
∑ = 120
∑ = (2×3−10) + (2×4−10) + (2×5−10) + (2×6−10)
∑ = -4 + -2 + 0 + 2
∑ = -4
4. 1 + 1/4 + 1/16 + 1/64 + 1/256
This is a geometric sequence where the first term is 1 and the common ratio is 1/4. The nth term is:
a = 1 (1/4)ⁿ⁻¹
So the series is:
5. -5 + -1 + 3 + 7 + 11
This is an arithmetic sequence where the first term is -5 and the common difference is 4. The nth term is:
a = -5 + 4(n−1)
a = -5 + 4n − 4
a = 4n − 9
So the series is:
