Hi!
First of all, we can look and see that these sqaure roots are the same, so it's easy to add.
In square roots, if the number INSIDE the square root is the same, it stays that way for the answer .
So the equation is 9(square root) 5 + 4(square root) 5.
The numbers out the sqaure root can just be added. So 9+4 = 13.
Lastly just attach the sqaure root onto the 13
Final answer should be 13(square root)5
***use the actual symbol in place of (sqaure root)
I hope this helps!
Answer:
four pack of notebooks for $4.56
Sides:
a = 19 m
b = 25 m
c = 31 m
Angles:
A = 37.7843 °
B = 53.7236 °
C = 88.492 °
Other:
P = 75 m
s = 37.5 m
K = 237.418 m2
r = 6.33114 m
R = 15.5054 m
Answer:
Step-by-step explanation:
By applying <em>Pythagoras theorem</em> we can find hypotenuse of a right angle triangle.
Side of right angle triangle (a) = 48 cm
Side of right angle triangle (b) = 14 cm
Hypotenuse² = a² × b²
The percentage searched is 4.2%
If you multiply some value to 1.042 this means that you are adding 4.2 %
See in the expression of formula that appears just the cited figure: "1.042"
