Equilateral triangle have the same side lengths. Perimeter = sum of all sides
(4x - 3) + (4x - 3) + (4x - 3) = 63
Remove parentheses
4x - 3 + 4x - 3 + 4x - 3 = 63
Combine like terms
12x - 9 = 63
12x = 72, x = 6
Solution: x = 6
Andy's family drove 3000 meters. 1 kilometer =1000 meters


Use quadratic formula to solve (shown in picture):
We would get two answers:
x = .3808
and
x = -18.381
Volume of a rectangular prism = w*h*l or Bh, where B is the BASE
432=B*9
432/9 = B
48=B
The base dimensions are 48 in^3
Well, to get the answer, we just divide 370 by 10.
370 divided by 10 = 37
So, the answer is 37
Hope this helped >.<
