Answer:
1. r = C/2π
2. A = π(C/2π)^2
Step-by-step explanation:
1. C = 2πr^2
C/2π = 2πr/2π
C/2π = r
r = C/2π
2. A = π(C/2π)^2
3. Look at screenshot
To simplify use the distributive property first. Multiply 6 by each value inside the parentheses:
6(x-4) + 9
6x -24 + 9
Now combine like terms to get the final answer:
6x - 15
One way working this out is to find all the numbers that go into 90 by listing all the pairs of numbers that multiply to give 90
1 × 90
2 × 45
3 × 30
6 × 15
9 × 10
From here we can do trial and error:
Let's choose any two factors, say 2 and 3
By listing their multiples, we will find their LCM is 6, not 90
Then choose any two factors, say 3 and 6
By listing their multiples, we will find their LCM is 6, not 90
We can try some bigger number, say 45 and 90
by listing their multiples, we will find their LCM 90
Answer: 45 and 90
Answer:
3 gallons of orange juice
√ 5 + √ 125 + 25 [original problem - I assume 25 is not under a root]
√5 + √ 25·5 + 25 [find perfect square factors of 125]
√5 + 5√5 +25 [simplify √125]
6√5 + 25 [add 1√5 + 5√5 together]
***If the 25 is under a root, simply take it's square root (5) and add it to the end of the problem. The answer would be 6√5 + 5***
