Answer:
178
Step-by-step explanation:
Use Pythagorean Theorem to find the Hypotenuse
30^2+72^2=78^2
Use perimeter formula
a+b+c
38+72+30
32 / (14 2/9) =
32 / (128/9) =
32 * 9 / 128 =
288 / 128 =
$ 2.25 per km

Answer:
38x^2 +14x -6
Step-by-step explanation:
SA = 2(LW +WH +LH)
= 2((4x +3)(x) +(x)(3x -1) +(4x +3)(3x -1))
= 2(4x^2 +3x +3x^2 -x +12x^2 +5x -3)
= 38x^2 +14x -6
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = -4
Hope this helps! :)
