Answer: 9a-9b-6
7(3a−2b)+5b−3(4a+2)
Distribute:
7(3a−2b)+5b−3(4a+2)
=(7)(3a)+(7)(−2b)+5b+(−3)(4a)+(−3)(2)
=21a+−14b+5b+−12a+−6
Combine Like Terms:
=21a+−14b+5b+−12a+−6
=(21a+−12a)+(−14b+5b)+(−6)
=9a+−9b+−6
We can simplify the exponent by multiplying 10 to itself 7 times.
= 10 * 10 * 10 * 10 * 10 * 10 * 10
= 100 * 10 * 10 * 10 * 10 * 10
= 1000 * 10 * 10 * 10 * 10
= 10000 * 10 * 10 * 10
= 100000 * 10 * 10
= 1000000 * 10
= 10000000
10^7 = <u>10,000,000</u>

Answer:
3
if a is 1 more than b it can be expressed as so:
a=b+1
b+1=a
b^2+1=a^2
b^2=a^2-1
b=a-1
if b if 1 then a is 2
b+1=a
-a+b=-1
a-b=1
a=2, b=1
a=b+1
a+b=3
1+2=3
Step-by-step explanation:
Using scientific notation, the power of 10 that should be put on the label is of , hence x = 7.
<h3>What is scientific notation?</h3>
A number in scientific notation is given by:
With the base being .
In this problem, we don't want to increase the base values much. Panama's population can be represented as:
Hence, the power of 10 that should be put on the label is of , hence x = 7.

The standard deviation of the exponential distribution is of 0.1.
-----------------
The exponential probability distribution, with mean and standard deviation m, is described by the following equation:
In which is the decay parameter.
-----------------
The distribution is described by:
- Which has
Thus, the mean and standard deviation are given by:
The standard deviation is of 0.1.
