Answer:
12,400
Step-by-step explanation:
so what you are going to first is 400 times 31 which is 12,400
We see that CF and DE are parallel to each other, which means that they had the same length with each other, so:
6n-1=5n+9
Subtract 5n for both side
6n-1-5n=5n+9-5n
n-1=9
Add 1 for both side
n-1+1=9+1
n=10
CF=
6n-1
=6(10)-1
=60-1
=59
DE=
5n+9
=5(10)+9
=50+9
=59
CD/FE:
4n+2
=4(10)+2
=42
True/False:
n=10 True
n=7 False
CF=59 True
FE=42 True
CD=30 False. As a result, n=10;CF=59; and FE=42 is your final answer. Hope it help!
Hello!
I will make approximations below to the nearest whole number
A. 2√32≈11
B. 5+√18≈9
C. √24≈5
D. √52-3≈4
E. 3√14≈11
F. √20+√26≈10
Based off of what we see here our even numbers are 
and 
.
I hope this helps!
2/3 x 5 = 3
the ratio from 4 to 20 is 5, then you multiply it by the original amount
so it's 3
