Answer:
Bc = 2
Step-by-step explanation:
Just add AB + CD
you'll get 19
substract it from AD
21 - 19 = 2
In Above question b = 39°
Not 31
BC=2
The equation is
AB+BC+CD=21
7+BC+12=21
19+BC=21
BC=21-19

2
2 because 6 multipled by 1/3 is 2 and 2 multipled 3 is 6
21
f(x) = 2x^2 + 3
f(-3) = 2(-3)^2 + 3
f(-3) = 2(9) + 3
f(-3) = 18 + 3
f(-3) = 21
