Answer:
The value of 'x' is 31 unit
Step-by-step explanation:
Given:
Measure of each side =
Perimeter of sails = 63 units.
We need to find the value of x.
Solution:
Now we can see that from given data.
A sailboat's Saul has three sides.
Now assuming it to be triangle we get;
"Perimeter of triangle is equal to sum of all side."
So we can say that;
Now adding both side by 30 we get;
Now dividing both side by 3 we get;
Hence the value of 'x' is 31 units.
Answer:
Step-by-step explanation:
Let's apply the formula (x+y)² = x² + 2xy + y²
Here, x = -a and y = b
So,
= (-a)² + 2(-a)(b) + (b)²
= a² - 2ab + b²
Hence, it has been proved that (-a + b)² = a² - 2ab + b².
Hope this helped!
