Answer:
a) x = 5
b) x = 4
Step-by-step explanation:
a) x = 5
You can get this with a calculator if you need by using the log function.

x = 5
b) x = 4
According to the product rule of exponents: 
So, x + 11 = 15 --> x = 4
Answer:
A= 1038 in²....
Step-by-step explanation:
There are several ways to find the area of a regular hexagon
In a regular hexagon, split the figure into triangles.
Find the area of one triangle.
Multiply this value by six.
We will apply the formula of area of regular polygon:
A= 1/2r²nsin(360/n)
r = radius
n = number of sides of the regular polygon
We know that,
r= 20 in
n= 6
Now substitute the values in the formula:
A= 1/2(20)²(6)sin(360/6)
A= (20)²(3)sin(360/6)
A= (20)²(3)sin(60)
A=3*(20)² *√3/2
A= 1200 * √3/2
A= 600*√3
A= 1038 in²....
Therefore the approximate area of hexagon is 1038 in²....
Let the income of first person be 9x
let the income of the second person be 7x
difference b/w their weekly income=9x-7x=200
=2x=200
x=100
therefore income of first person is 9x=9×100=RS 900
therefore income of second person is 7x=7×100=RS 700
Answer:

√159= 12.6 <----- answer
For the first one
1 hour = 15 miles
If Caleb traveled for 3 hours you multiply 15 by 3
3•15= 45
So Caleb traveled 45 miles
