You could do the negative square root of 16 and the negative square root of 25 to get -4 and -5. So this means the answer is negative square root of 20 is in between -4 and -5
So the total price would be 100% + 8% tax = 108% of the original price. Since 108% written as a decimal is 1.08, we can do the following:
5,000 * 1.08 = 5,400
Answer:

Answer:
B 7
Step-by-step explanation:
Since the triangles are similar by AAA
We can use ratios to find the length x (which is PR)
5 15
-------- = ------------
x 21
Using cross products
5 * 21 = 15 *x
Divide each side by 15
5/15 * 21 = 15x/15
1/3 * 21 =x
7 =x
3x + 4(x + 1) = 67
7x + 4 = 67
7x = 67-4 = 63
x = 9
The smaller integer is 9.
