Answer:
12.1 km
Step-by-step explanation:
350 * 2 = 700
200 * 2 = 400
700 + 400 = 1100
1100 * 11 = 12100
12100 / 1000 = 12.1
12.1 km
40×4×4=640
b=20 h=4
using formula:
1/2×base×height
1/2×20×4=40
its says scale by factor 4:
b=80 h=16
using formula:
1/2×base×height
1/2×80×16=640
answer------>>>>640cm^2
5/8 would be the simplest form for 10/16 .
The common factor of given terms is x/8, which is given in option B.
<h3>What is factor?</h3>
A factor is a number that divides another number, leaving no remainder.
Here, given terms are:
and 
Now, factors of 5x/8 = 5 X 1/8 X (x)
factors of 11x/8 = 11 X 1/8 X (x)
So, common factors are 1/8 and x
Thus, the common factor of given terms is x/8, which is given in option B.
