Answer:
3 
Step-by-step explanation:
1 1/9 + 2 = 3 1/9
The answer is 126in^2. The formula for calculating trapezoid is A=a+b/2(h). Area=base 1+base 2 divided by 2 times height. Base 1 is 12in. Base 2 is 2in+2in+12in=16in. And the height is 9in. So 12in+16in=28in. 28in/2=14in. 14in(9in)=126in^2.
**Note ^ before a number tells someone the number after it will be an exponent**
There must be 23 students in Ms.Gardner's class because 23 - 30%=6.9 so 7
students are in her class are in the play because if you look at
Mr.Logan's class he has 23 students to and there are aslo 7 students in
his class are in the play so Mr. Logan's class is basically is holding
Ms.Gardner's place
3x-4=-31
+4 +4
3x=27
X=9
Hope this helps
