X² - 64 = 0
(x - 8)(x + 8) = 0
x = - 8, 8
Your other solution is - 8
Answer:
Principal amount (P) = $10,000
Rate (R) = 1.5%
Time (T) = 4 years
Simple interest, I = P X R X T / 100
= 10000 X 1.5 X 4 /100
= 60000 / 100
= $600
Therefore, Balance = P + I
= 10000 + 600
= $10600
-1 1/4 as a decimal would be -1.25.

Amount of tax on the book (s) is $0.72
Step-by-step explanation:
- Step 1: Given 6/100 = s/12

⇒ 72 = 100s
⇒ s = 72/100 = 0.72
The answer is ( -2 , -1 ) .
Hope it's helped ♥️♥️♥️♥️♥️.
