The question we need to ask is what percent of 2 is 40?
40 is 20 times 2 so 20 would be 2,000%
We need to subract 100% from any percent change:
2,000% - 100% = 1,900%
ANSWER: 1,900%
Answer:
The answer is -86
Step-by-step explanation:
-7 squared is 49
49 × 2 = 98
12-98= -86
Substitute -2 in for x and get (9)^-2
Flip the equation so that the exponent is positive and get 1/9^2
Work it out 1/(9*9) = 1/81
The answer is B, 15,504.
The reasoning is 20C15.
