233.3333333. and you cant sell .333 of a book so 234 books
14.5% = 0.145 = 145/1000
14.5 = 14500/1000
So 14.5% is a hundredth the size of 14.5, so they are not equal and the friend is incorrect.
Step-by-step explanation:
- 9x-3=60°{each angle of equilateral triangle is 60°}
- 9x=60+3
- x=63/9
- x=7
so,
hope it helps.
Answer:
B) f(x) = 3x² - 2x + 5
Step-by-step explanation:
To find the correct quadratic function that represents the table, you must substitute [x] into the quadratic function.
A) f(x) = 3x² + 2x - 5
B) f(x) = 3x² - 2x + 5
C) f(x) = 2x² + 3x - 5
D) f(x) = 2x² - 2x + 5
A. 3(-2)² + 2(-2) - 5 =
3(4) - 4 - 5
12 - 4 - 5
12 - 9
= 3
B. 3(-2)² - 2(-2) + 5 =
3(4) + 4 + 5
12 + 9
= 21
C. 2(-2)² + 3(-2) -5 =
2(4) - 6 - 5
8 - 11
= - 3
D. 2(-2)² + 2(-2) + 5 =
2(4) - 4 + 5
8 - 4 + 5
8 + 1
= 9
Your correct answer is: B
