Answer:
Whats A?
Step-by-step explanation:
Answer:
z=1.5
Step-by-step explanation:
Simplifying
6z + 3 + -4z = 9
Reorder the terms:
3 + 6z + -4z = 9
Combine like terms: 6z + -4z = 2z
3 + 2z = 9
Solving
3 + 2z = 9
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + 2z = 9 + -3
Combine like terms: 3 + -3 = 0
0 + 2z = 9 + -3
2z = 9 + -3
Combine like terms: 9 + -3 = 6
2z = 6
Divide each side by '2'.
z = 3
Simplifying
z = 3
Answer:
20.49 feet to the nearest hundredth.
Step-by-step explanation:
Using the Pythagoras Theorem:
38^2 = h^2 + 32^2
h^2 = 38^2 - 32^2
h^2 = 420
h = √420
h = 20.494 m.
X to the second power=9x^2=9
