(m+11n)^2
=(m+11n)(m+11n)
=m^2+11mn+11mn+121n^2
=m^2+22mn×121n^2
For Example;
use FOIL: (a+b)(a+b)
First. a^2
Outside. ab
Inside. ab
Last. b^2
Answer:
5/(6*2*1/2)
Step-by-step explanation:
No matter where you put the parenthesis it stays the same answer. :)
Answer:
The length of the hypotenuse ≈ 39.7 cm
Explanation:
Since the given triangle is a right-angled triangle, this means that we can apply the Pythagorean theorem.
The equation for Pythagorean calculation is:
(hypotenuse)² = (first leg)² + (second leg)²
In the given, we have:
first leg = 30 cm
second leg = 26 cm
Substitute with the givens in the above equation to get the hypotenuse as follows:
(hypotenuse)² = (30)² + (26)²
(hypotenuse)² = 1576
This means that:
either hypotenuse = √1576 = 39.69 ≈ 39.7 cm ..........> accepted
or hypotenuse = -√1576 = -39.69 ......> rejected as length can't be negative
Hope this helps :)
