I'd start by listing out the multiplies of all three past 100, like this:
102, 104, 106, 108, 110, 112, 114, 116, 118, 120, 122, 124, 126, 128, 130
104, 108, 112, 116, 120, 124, 128, 132, 136
110, 120, 130, 140
Now it's just a matter of finding the number that is the same for all three of them, which is 120.

Answer:
$3.90
Step-by-step explanation:
The total cost was $24.40.
We know the cost for beads for each necklace is also $2.20, multiply this by four to find the cost of the beads for all the necklaces.
$2.20 × 4 = $8.80
Now we will subtract this from the total price.
$24.40 - $8.80 = $15.60
$15.60 Is the remaining cost for the pendants of all four necklaces. We will now divide this by four to find the price of a single pendant.
$15.60 ÷ 4 = $3.90
<u>This means the cost of each pendant is $3.90</u>
Answer:
18.135
Step-by-step explanation:
9.75*30=292.5
6.2%*292.5=18.135

Answer:
x^2 -5x +14 = 10^(2x +4)
Step-by-step explanation:
The relationship is ...
log(a) = b ⇔ a = 10^b
__
Using this with a=x^2-5x+14 and b=2x+4, we have ...
x^2 -5x +14 = 10^(2x +4)

<em>Additional comments</em>
In plain text, the exponent needs parentheses, because superscript formatting is not available to tell what is and isn't part of the exponent.
The base of "log" is assumed to be 10 in high school algebra. In the larger world, "log" is often used in place of "ln" to mean the logarithm to base 'e'.

The one solution is approximately x = −1.32505947996.
