Answer:
+2 ft
Step-by-step explanation:
He descends -12 feet (negative descend is an ascend) so he ascends 12 feet
-14 + 12 = -2 so he needs to travel 2ft

Answer:
20 miles
Step-by-step explanation:
I set this up as a linear equation:
45 + x = 25 + 2x
1. subtract x from both sides
45 = 25 + x
2. subtract 25 from both sides to isolate the variable
20 = x
The height would be 3.7
Because it's an isosceles triangle, you and I know that the sides are 4 and the base is 3. We also know that to find the height we need to use Pythagorean's theorem. Therefore, h square + 1.5 square = 4 square (we get 1.5 from dividing 3 to get the base). Solve it and the height is 3.7
X^3
We want to cube root it to find what number is multiplied three times to get it
For example
64
4 * 4 * 4
= 64
X^3
If we put the number 2 where the x is
2^3
That is
8
The cubed root of 8 is 2
And 2 was where x was
X^3
Is just x
As x * x * x = x^3
