Answer:
6.4 x 7.4 =47.36
Step-by-step explanation:
7.35 rounded will be 7.4
You would need 31 Vans for everyone to be transported.
If the perimeters are equal, you can form an equation to find x:
x + x + 12 + x + x + 12 = x + 11 + x + 11 + x + 16
4x + 24 = 3x + 38
- 3x
x + 24 = 38
- 24
x = 14
Now you can substitute the x value into the perimeter:
(4 × 14) + 24
56 + 24 = 80 cm
(3 × 14) + 38
42 + 38 = 80 cm
So the perimeter would be 80 cm.
I hope this helps!
A - bi would be the other complex zero.
When you take the sqrt when solving an equation you get a + and - solution.
6 and 8 I believe is the answer
