Answer:
Simplifying
2x(3x + -8) = 0
Reorder the terms:
2x(-8 + 3x) = 0
(-8 * 2x + 3x * 2x) = 0
(-16x + 6x2) = 0
Solving
-16x + 6x2 = 0
Solving for variable 'x'.
Factor out the Greatest Common Factor (GCF), '2x'.
2x(-8 + 3x) = 0
Ignore the factor 2.
Subproblem 1
Set the factor 'x' equal to zero and attempt to solve:
Simplifying
x = 0
Solving
x = 0
Move all terms containing x to the left, all other terms to the right.
Simplifying
x = 0
Subproblem 2
Set the factor '(-8 + 3x)' equal to zero and attempt to solve:
Simplifying
-8 + 3x = 0
Solving
-8 + 3x = 0
Move all terms containing x to the left, all other terms to the right.
Add '8' to each side of the equation.
-8 + 8 + 3x = 0 + 8
Combine like terms: -8 + 8 = 0
0 + 3x = 0 + 8
3x = 0 + 8
Combine like terms: 0 + 8 = 8
3x = 8
Divide each side by '3'.
x = 2.666666667
Simplifying
x = 2.666666667
Solution
x = {0, 2.666666667}

38 feet
In the first example the tree was 30 feet but the shadow was 10 feet taller due to the angle of the sun. Assume a 38 foot tree if right there with the same angle of the sun on it, then the shadow will also be 10 feet taller , 48 feet.
Answer:
a = 31.7
c = 39.1
Step-by-step explanation:
tan54 = a / 23
a = 23 * tg54
a = 31.7
sin54 = 31.7 / c
c = 31.7 / sin54
c = 39.1
