For this case we must find an expression equivalent to:
By definition of power properties we have to meet:
So, rewriting the expression we have:
Answer:
Option B
Answer:
16 ft
Step-by-step explanation:
Based on the situation above, it forms into a right triangle. Therefore we can apply the Pythagorean Theorem. We will use the formula below:
c = √( a² + b²)
In the problem above, the ladder acts as the hypotenuse denoted by c. It has a length of 20 ft. While the base denoted by b is 12 ft. Therefore, we need to solve for a. We will derive the formula above.
c² = a² + b²
a² = c² - b²
a = √( c² - b² )
a = √( 20² - 12² )
a = 16
The unit is in ft.
Correct me if I'm wrong. I hope it helps.
I believe the answer is B. 39, 49, 59
Answer:
Step-by-step explanation:
both represent the same line .
Hence it has infinite solutions as there are infinite points on aline.
