Start by dividing both sides by 2 to get

. Doing the math on the right, keeping in mind that logs have an unwritten base of 10, gives us

. Rewriting this in exponential form is

. That means that x = 8. Not negative, only positive.
Answer:
8.94 (Rounded would be 9)
Step-by-step explanation:
By using the Pythagorean Theorem formula,
A^2+B^2 = C^2
You have the hypotenuse (c) = 12
and you have a leg (a) = 8
and you're trying to find another leg (b) = x
In order to find this, you'll have to change up the formula in order to find (B) instead of (C)
B^2 = C^2 - A^2
(B) = (12)^2 - (8)^2
(B) = 144 - 64
(B) = 80
Square root of 80
B = 8.9
Answer:

Step-by-step explanation:
The area of a circle is given by
where
is the radius of the circle. The diameter is given as
feet, so the radius of this circle is
feet.
Plugging in our values, we get:
.
Answer:
I failed math twice
Step-by-step explanation:
Uhm, I'm pretty new to expanded form but I think it's something like:
(3 × 1/10) + (1 × 1/100) + (6 × 1/1000)
You can also write it as:
0.3 + 0.01 + 0.006
Let me know if you need working or anything!
