Answer:
k = 25
Step-by-step explanation:
(2x - sqrt(k) )^2 Expand this as a binomial
4x^2 - 4x*sqrt(k) + k The middle term must be -20x Solve for k so it is
-4xsqrt(k) = - 20x Divide by -4x
sqrt(k) = -20x/-4x Do the division
sqrt(k) = 5 Square both sides
k = 25

Answer:
√85
Step-by-step explanation:
The given shape is a right angled triangle.
Let the missing side length be " x ".
By Pythagoras theorem,
x² = 6² + 7²
x² = 36 + 49
x² = 85
x = √85
Therefore, the missing side length be √85.

Answer:
11.2 feet
Step-by-step explanation:
Given: Height of platform (Opposite)= 5 foot
Distance of slope from the base of platform (adjacent)= 10 feet
Picture drawn to show the measurement.
Lets find the length of slope.
Using the Pythagorean theoram.

Subtituting the value in the formula.

⇒ 
⇒ 
Putting square root on both side
We know, √a²= a
⇒ 
∴ hypotenous= 11.18 
Hence, the slope is 11.2 feet
