Answer:
Step-by-step explanation:
Use identity -
(a+b)² = a²+b²+2ab
(5+√3)² = 5²+(√3)² + 2(5)(√3)
= 25 + 3 + 10√3
= 28 + 10√3
= 2(14+ 5√3)
Answer:
The distance from his starting point is <u>6.7 m</u>.
Step-by-step explanation:
Given:
Shane marched 3 m East and 6 m north.
Now, to get the distance from his starting point.
Let the distance from the starting point be 
Now, to solve using pythagorean theorem:




<em>Using square root on both sides we get:</em>

<u>So, the distance from the starting point nearest to tenth is 6.7 m.</u>
Therefore, he is 6.7 m from his starting point.
Answer:
x = 13/5, 11/15
Step-by-step explanation:
(11x - 15) (5x - 13)
