Answer:
First option: 6y^2sqrt(10) + 12sqrt(5y)
Step-by-step explanation:
3sqrt(10) * (2y^2 + 2sqrt(2y)
= 6y^2sqrt(10) + 6sqrt(20y)
= 6y^2sqrt(10) + 12sqrt(5y)
A = the number before x^2 = 3
b = the number before x = 5
To find the axis of symmetry: -b/2a
x = -5/6
Answer:
m=3
Step-by-step explanation:
expand and move the terms around
18m+4-1=27+10m
8m=24
m=3
Answer:
d. 60
Step-by-step explanation:
According to Gay Lussac's Law
P1/T1=P2/T2 where
P1= Pressure at the start, T1 = initial Temperature
, P2= Final Pressure, T2 =Final Temperature
T1=P1*T2/P2= 7*420/49=60
Answer:
3(2y+1)-3y=15 y=4
Step-by-step explanation:
substitute x=2y+1 into x then solve for y
