Pense un numero, lo eleve al cuadrado, despues lo multiplique por 10 y obtuve 40 ¿Que numero es?

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

explanation:

step-by-step explanation:

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )

is this the complete
