Write an equation for the description. The sum of 15 and a number x is equal to 18.

There is not enough description provided. So i will solve this to the best of my ability.

x+15=y

x=18

3 qrs + 3/2 xy hope this : /

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! )
