The value of √-9 is not -3 because_______.A. 9^2 not congruent to -3
B. (-3)^2 not congruent to -9
C. 3^2 not congruent to -9
D. (-9)^2 not congruent to -3

Answers

Answer 1

Answer: B, because -3^2 is not -9. -3*-3 = 9, square roots of negative numbers aren't possible, because no number squared can be equal to them. Instead, they are expressed in terms of "i", which is defined as

i^2 = -1

Answer 2

Answer: The value of √-9 is not -3 because B. (-3)^2 not congruent to -9.

This is the answer because, (-3)^2 = 9 NOT -9. Any negative squared is equal to the positive squared. E.g. 2^2=4 & (-2)^2=4. Another tip is that in the number in the square root sign is negative the answer is no solution as it is impossible to square a number and get a negative answer.

An article retails for $38.50. The city sales tax is 4%, and the federal excise tax is 7%. How much is the total tax?

Answers

4/100; 38.50 x 0.04= $1.54
7/100; 38.50 x 0.07= $2.70

$1.54 + $2.70= $4.24

First you add the two tax percentages together- 11%
Then you must find what 11% of $38.50 is;
So, you multiply $38.50 by .11; which is the equivalent of 11% of the total.
This equals $4.235, which would be your total tax.
