Answer:C or 11
Step-by-step explanation:
3x²-1
First you insert x... which is 2
3(2)²-1

Answer:
It is because you have to get rid of the power of 2 from c. In order to get rid, you have to square root it on both sides :
c² = 74
√(c²) = √74
c^(1/2×2) = √74
c = √74
Using Indices formula, (a^m)^n = a^(mn)
