Answer:
3.
equation = 
Using:
or 
or
7^2 + 12^2 = c^2
49 + 144 = c^2
c^2 = 193
missing length = 13.9 inches
4. equation = 
Using:
or
24^2 + 32^2 = c^2
reduce to:
8 multiplied by everything:
3^2 + 4^2 = c^2
Since we know 3,4,5 is a Pythagorean triple, we can use this to find c.
Since c must be 5, we multiply by 8 since we divided by 8 earlier to get the 3,4,5 and get 40.
missing length = 40 inches
Answer:
12
Step-by-step explanation:
4u - 8u = -63 + 15 ( collecting like terms)
-4u = -48
u = 12
Answer: x=5
Simplifying
5(x + -2) = 15
Reorder the terms:
5(-2 + x) = 15
(-2 * 5 + x * 5) = 15
(-10 + 5x) = 15
Solving
-10 + 5x = 15
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '10' to each side of the equation.
-10 + 10 + 5x = 15 + 10
Combine like terms: -10 + 10 = 0
0 + 5x = 15 + 10
5x = 15 + 10
Combine like terms: 15 + 10 = 25
5x = 25
Divide each side by '5'.
x = 5
Simplifying
x = 5
