Step-by-step explanation:
sum means add
(3x+2)(3x+2) = 6x+4
A would be the closest estimate
Answer:
using pythagoras theorem
a^2+b^2=c^2
8^2+x^2=(x+2)^2
64+x^2=x^2+2*x*2+2^2
64+x^2=x^2+4x+4(here x^2 of left hand side and x^2 of right hand side gets cancel)
64=4x+4
64-4=4x
60/4=x
15=x
Step-by-step explanation:
Answer:
500 liters
Step-by-step explanation:
P=k/V
10=k/150
1500=k
k=1500
3=1500/V
3V=1500
V=500
