Answer: 45.. i think.
Step-by-step explanation: I couldn't really get the measurements from this photo so here is what I got. I used the formula A=a+b over 2 times h. I used 7=a, b=11,h=5. I added 7 and 11 to get 18, then divide that by 2, which equals 9. Then 9 times 5 = 45. I hope this somewhat helps.

Answer:
-5 or 5=y
Step-by-step explanation:
6y-5=7y-y
6y-5=6y
-6y -6y
-5=0y
÷0 ÷0
-5 or 5= y
Answer:
20000
Step-by-step explanation:
2.8*10^7 = 28000000
1.4*10^3 = 1400
28000000/1400= 20000
Hope this helped!!
Answer:
{-7, 2, 8}
Step-by-step explanation:
We see that the domain is limited to three x-values: -3, 0 and 2. To find the range (which is the set of all y-values) we just need to plug-in these x-values and find the corresponding y-values.
So our equation is:
y = 3x + 2
Then we substitute for the x-values:
y = 3(-3) + 2
y = -9 + 2
y = -7
y = 3(0) + 2
y = 0 + 2
y = 2
y = 3(2) + 2
y = 6 + 2
y = 8
So our range would be {-7, 2, 8}.
