Plz answer both of these, making this worth several points:
a rectangle has length 10 feet and width 6 feet. it is enlarged to a similar rectangle with length 18 feet. what is the new width?

if 200 vitamins cost $4.75, what should 500 vitamins cost?

Length:Width 10:6 18:x Cross multiply; 10x/6x18 108/10x; x=10.8 200=$4.75 500=x Cross multiply 4.75x500/200x x=11.875

Step-by-step explanation:

7. d. 64

8. i. 32

9. c. 125

10. j. none of the above

11. d. 81

12. i. 216

13. e. none of the above

14. g. 240

15. e. none of the above

16. g. 32

17.   e. none of the above

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
