Answer:
See below
Step-by-step explanation:
<u>We can estimate the dividend and divisor as follows:</u>
- 635943 ÷ 77 =
- 636000 ÷ 80 =
- 7950 ≈ 8000
Estimate is 8000
N=number of nickles
d=number of dimes
q=number of quarters
use cents for everything
total value=585
5n+10d+25q=585
divide everybody by 5 to simplify
n+2d+5q=117
we have
nicles are 5 more than quarters
n=5+q
4 times as many dimes as quarters
d=4 times q
d=4q
sub those in
5+q+2(4q)+5q=117
5+6q+8q=117
5+14q=117
minus 5
14q=112
q=8
sub back
n=5+q
n=5+8
n=13
d=4q
d=4(8)
d=32
13 nickles
32 dimes
8 quarters
divide both sides by 22
Answer
-18√2-6√6
Step-by-step explanation:
(√12 +6) (-√8-√2)
=√12(-√8-√2)+6(-√8-√2)
= -√96-√24-6√8-6√2
= -4√6-2√6-12√2-6√2
= -6√6-18√2
= -18√2- 6√6
