Answer:
5√3
Step-by-step explanation:
The <em>geometric mean</em> (GM) of two numbers x and y is the square root of their product.
Thus, the GM of x and y is √(xy).
The GM of 3√5 and 5√5
= √(3√5 × 5√5)
= √[3 × 5 × (√5)²]
= √(3 × 5 × 5)
= √(3 × 5²)
= 5√3

Answer:
12, 17, 24
Step-by-step explanation:
To find the first 3 terms, substitute n = 1, 2, 3 into the rule, that is
T₁ = 1² + 2(1) + 9 = 1 + 2 + 9 = 12
T₂ = 2² + 2(2) + 9 = 4 + 4 + 9 = 17
T₃ = 3² + 2(3) + 9 = 9 + 6 + 9 = 24
x = 2
Step-by-step explanation:
3(x + 1) - 2 = x + 5
3x + 3 - 2 = x + 5
3x + 1 = x + 5
3x - x = 5 - 1
2x = 4
x = 4 / 2
x = 2
31. At the candy store:
=> Ericka bought 3 kilograms of Cinnamon red hots and 1 kilograms of gummy bears for 21.00 dollars.
=> Irene bought 3 kilograms of cinnamon red hots and 3 kilograms of gummy bears for 39.00 dollars.
Question: Find the costs of each kilograms.
Notice that the cinnamon red hot that they both are the same, the only difference is the gummy bears, which added 2kilos for Irene.
Now, let’s subtract
=> 39 – 21 = 18 dollars – this is the costs of 2 kilos of gummy bear
=> 18 / 2 = 9 dollars, thus the price of each kilos of gummy bear is 9 dollars,
Now, let’s solve for the cinnamon
=> 21 – 9 = 12 dollars, to be divided with 3 kilos
=> 12 / 3 = 4 dollars – the price of cinnamon red hot per kilo.
