C. trapezoid
a trapezoid's legs are congruent, while the bases are symmetrical
a square is the answer you would want, because it is always true, while a trapezoid is only "sometimes" true
thanks Kaikers :D
Since there are 21 questions and one is extra credit, the fraction is 21/20. Divide it to get 1.05. In percent, this is 105%. Hope this helps!
Answer:
(20a+108)/15
Step-by-step explanation:
First find LCM of the denominators. U will find it to be 15
Then calculate the number like this.
[(14a)×1/15×1]+[(2a+36)×3/5]
[(14a/15)]+[(6a+108)/15
(14a+6a+108)/15
(20a+108)/15
This would be 198 because 12 times 1.5 equals 18 so when you multiply 132 by 1.5 you get 198
