The answer is... 80%, 85%, and 90%.
4/5=80%
17/20 =85%
9/10=90%
4 - 36 / 3 * 4
1. PEMDAS = parenthesis, exponents, multiplication, DIVISION, addition, subtraction.
4 - 12 * 4, because 36 / 3 is 12
2. PEMDAS = parenthesis, exponents, MULTIPLICATION, division, addition, subtraction.
4 - 48, because 12 * 4 is 48
Answer is -44.
f(x) means you sub in the number for x in this situation it would be -2 so
f(x)=-(-2)^3+2(-2)-1
8-4-1

Answer:
f(x) = (x+6)² - 10
Step-by-step explanation:
To write the equation in vertex form we, we need to use completing square method.
f(x) = x²+ 12x + 26 = (x² + 2*x*6 + 6²) - 6² + 26 = (x+6)² -36 + 26 =
= (x+6)² - 10
f(x) = (x+6)² - 10
