A.3n+4+3n+4+4n
=3n+3n+4n+4+4
=10n+8
B.11n+4+n-12
=11n+n+4-12
=12n-8
C.6(6n-2)
=36n-12
D.4(3n-2)
=12n-8
E.4n+22-12+8n
=4n+8n+22-12
=12n+10
so,B and D are the expressions that are equivalent to 12n-8.
Answer:
9 + 10 = 21
Step-by-step explanation:
9 + 10 = 21
Factor out 9 and 10
9 = 3 · 3 10 = 2 · 5

3 × 2 = 6
Then multiply 3 by 5
3 · 5 = 15
Finally add the products
15 + 6 = 21
Answer:
3 inches
Step-by-step explanation:
We can use proportions to solve. Put the map on top and the real life size on bottom.
1 inch x inches
------------- = -------------
4 ft 12 ft
Using cross products
1 * 12 = 4 * x
Divide each side by 4
12/4 = 4x/4
3 =x
3 inches
