7x(√x - 7√7) Multiply √7x to "√x" and "-7√7" respectively:
√7x*√x - 7√7*√7x
First is to simplify: √7x² - 7√7²x
Extract the squares: x√7 - 7*7√x
Then, we simplify: x√7 - 49√x
After simplifying the equation, I got the answer x√7 - 49√x.
Answer:
Step-by-step explanation:
We are given the following in the question:
Let the equation:
be the linear equation that represent temperature at an elevation x.
Temperature at 6000-foot level = 76 f
Temperature at 12000-foot level = 49 f
Solving the two equation, we get,
Thus, we can write the linear equation as:
We can think of this as a right triangle, where the given lengths are the legs.
So, we can solve using the Pythagorean Theorem.
21² + 28² = c²
441 + 784 = c²
1225 = c²
35 = c
