To find the perimeter of the square, you add all four sides together:
10x + 10x + (6x + 8) + (6x + 8)
20x + 12x + 16 = P
32x + 16 = P
you have to find x to get the actual perimeter. Since the shape is a square, all 4 sides are equal, so you can set 10x and (6x + 8) as equal to each other.
10x = 6x + 8
4x = 8
x = 2
Now you just plug in x and finish the rest of the problem, and you have the answer:
32(2) + 16 = P
64 + 16 = P
P = 80
(if you find this helpful, marking this as the brainliest answer would make my day :)
Answer:
i think for the first one i think it would be 250mm
and the second one would probably i think 1500
Step-by-step explanation:
I answered it in a table as seen above, place the amount in terms of X and then work out what X is equal to
Answer: r=C/2π
Step-by-step explanation:
Circumference= 2πr
C=2πr
Divide both side by 2π
C/2π = 2πr/2π
r = C/2π
