My way is 14.50/100 to give you one percent. So one percent is .145 mutiply that by 7 to give you 1.02 so 14.50+1.02=15.52. So 15.52 is the answer.
Answer:
<h2>9</h2>
Step-by-step explanation:
9 1/3 is 9.333333333 but you only need the 9.333. So you look at the 3 after the nine. 4 or below goes to the number lower and 5 or higher goes to the number higher. So in this case 9.3 the 3 is smaller than 4 so therefore the number is smaller so it stays nine.
Answer:

Step-by-step explanation:

3 - 75x³ ← factor out 3x³ from each term
= 3x³(x² - 25) ← this is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , thus
x² - 25 = x² - 5² = (x - 5)(x + 5)
Thus
3 - 75x³ = 3x³(x - 5)(x + 5)
(44)
81c² + 72c + 16 ← is a perfect square of the form
(ac + b)² = a²c² + 2abc + b²
Compare coefficients of like terms
a² = 81 ⇒ a = = 9
b² = 16 ⇒ b = = 4
and 2ab = 2 × 9 × 4 = 72
Thus
81c² + 72c + 16 = (9c + 4)²
Because the 16 is inside the parentheses also.
