Answer:
you would mark the different points less than 250 and then you plot the inequality from the previous questions.
Yes because you subtract seven from 331 and that gives you 324 and you divide 324 divided by 6 and that gives you 54
Answer: x+4
Step-by-step explanation:
(x-9)(x+4)= x^2-5x-36
Answer:
(x + 9)² = 36
Step-by-step explanation:
Given
x² + 18x + 57 = 12 ( subtract 57 from both sides )
x² + 18x = - 45
To complete the square
add ( half the coefficient of the x- term)² to both sides
x² + 2(9)x + 81 = - 45 + 81
(x + 9)² = 36
