## anonymous one year ago How is the expression (5 + y) ⋅8 described by its factors and terms? It has two factors and the factor (5 + y) has one term. It has three factors and the factor (5 + y) has one term. It has three factors and the factor (5 + y) has two terms. It has two factors and the factor (5 + y) has two terms.

how many terms are there in 5 + y ?

5. anonymous

@welshfella im back. 2 terms. yes?

6. welshfella

right and factors are things that multiply each other like (3 - y) . 4 - two factors 4 and (3 - y)

7. anonymous

ok so two terms and two factors?

8. welshfella

right

ty

i got one more.

The four points (−2, 5), (−2, −1), (5, −1), and (3, 5) are the vertices of a polygon. What is the area, in square units, of this polygon? 27 units2 33 units2 36 units2 51 units2

13. anonymous

btw the 2 after the word units is to the second power.

14. welshfella

you can draw a rough diagram

uh.. i cant really count inbetween those.. its kinda hard to read xD as well as a real graph would have the lines for cubes and the extra numbers.

19. anonymous

i got 19

20. welshfella

so you can either use the area formula for a trapezoid or split it into a rectangle and triangle

21. anonymous

oh wait wrong way of doing this xD i get it now hold on.

22. anonymous

i got 45.5

23. welshfella

I get it 42 but thats not one of the options Maybe I plotted it it wrong.

24. welshfella

area of the rectangle = 5 * 7 = 35 area triangle = 1/2 * 2 * 7 = 7 total 42 units ^2

25. anonymous

but thats not an answer.

27. welshfella

yea i know . Can't see where i went wrong though.

28. anonymous

i dont see where u went wrong either maybe just start fresh.

29. anonymous

(−2, 5), (−2, −1), (5, −1), and (3, 5)

30. welshfella

yea i see where i went wrong the height is 6 not 7 |dw:1440792187204:dw|

31. welshfella

so that comes to 6 * 5 + 0.5*2 * 6 = 30 + 6 = 36 unit^2

32. anonymous

there we go :D

33. welshfella

gotta go right now
