The answer is 1625
Answer:
62.34
Step-by-step explanation:
Substitute n = 0 to n = 5 into the expression and sum the terms, that is
3 [ 
+ 
+ 
+ 
+ 
+ 
]
= 3 [ 1 + 
+ 
+ 
+ 
+ 
]
= 3( 
)
= 3 × 20.781
= 62.34 ( to the nearest hundredth )
Answer:
x=2
Step-by-step explanation:
5(x+3)-2=13
5(x+3)=15
x+3=5
x=2
When you write that equation, you get 3x^2+6=81.
Solving for x:
Subtract by 6 on both sides of the equation to get 3x^2=75.
Then, divide by 3 on both sides of the equation to get x^2=25.
Finally, do the square root on both sides of the equation to get x=5.
The number is 5.
