The area of a square is its side length squared. So the side length of the square squared is 42, so the side length of the square is sqrt(42). The perimeter of the square is 4 times the side length, or 4sqrt(42), which is approximately 25.92.
Answer:
x = 3/4 or 0.75
Step-by-step explanation:
Break the bracket out and you will get:
3(5x – 4) – 2 = 10 – 3x
= 3*5x - 3*4 - 2 = 10 - 3x
= 15x - 12 -2 = 10 -3x
Add 3x into both sides and subtract 12 and subtract 2 in both sides, we get:
15x + 3x - 12 - 2 + 12 - 2 = 10 - 3x + 3x + 12 + 2
18x = 24
Divide both side by 18, we get:
18x/18 = 24/18
x = 24/18 = 3/4 or 0.75
Hope this helped :3
