Most of the square numbers are even.so if we need to find root over we need an even number to convert it to perfect square.

See the example below

  • P=3
  • B=4
  • H=5

\\ \ast\bull\rm\longmapsto H^2=P^2+B^2

\\ \ast\bull\rm\longmapsto H^2=3^2+4^2

\\ \ast\bull\rm\longmapsto H^2=9+16

\\ \ast\bull\rm\longmapsto H^2=25

\\ \ast\bull\rm\longmapsto H=\sqrt{25}

\\ \ast\bull\rm\longmapsto H=5

Some other triplets are

  • (6,8,10)
  • (5,12,13)
  • (8,15,17)

If QT = ST = 43 and m∠SRT = 42°, what is m∠QRS?<br><br> m∠QRS =
Korvikt [17]

Answer:

61 degrees

Step-by-step explanation:

m∡QRT=m∡SRT

5x – 9=2x + 33

3x=42

x=14

∡SRT=2x+33

∡SRT=2(14)+33

∡SRT=28+33

(2a^2 + ab +2b)+(4a^2-3ab+9)​
maw [93]

Answer:

-2 a b + 2 b + 6 a^2 + 9

Step-by-step explanation:

Simplify the following:

2 a^2 + a b + 2 b + 4 a^2 - 3 a b + 9

Grouping like terms, 2 a^2 + a b + 2 b + 4 a^2 - 3 a b + 9 = (a b - 3 a b) + 2 b + (2 a^2 + 4 a^2) + 9:

(a b - 3 a b) + 2 b + (2 a^2 + 4 a^2) + 9

a b + a b (-3) = -2 a b:

-2 a b + 2 b + (2 a^2 + 4 a^2) + 9

2 a^2 + 4 a^2 = 6 a^2:

Answer:  -2 a b + 2 b + 6 a^2 + 9
