Answer:
Step-by-step explanation:
x² - 24x + 5 = 0
x² - 24x = -5
Now divide the co efficient of x by 2 and square the quotient and add to both sides
24/2 = 12
12² = 144. Now add 144 to both sides of the equation.
x² - 24x + 144 = 5 + 144
x² - 24x + 144 = 149
x² - 2*12*x + 12² = 149
(x - 12)² = 149
Both sides take square root
x - 12 = ±√149
x = 12 ± √149
To solve the inequality -25 > -5(x + 2.5), first multiply -5 by the number and variable in the parentheses.
-25 > -5x - 12.5
Now add 12.5 to both sides of the equation.
-25 + 12.5 > -5x - 12.5 + 12.5
-12.5 > -5x
Now divide -12.5 by -5 to get the answer.
-12.5 ÷ -5 is 2.5
You would think the final answer is 2.5 > x, but that is not true because -5 is negative and when a negative number is divided to both sides of an inequality, the sign gets flipped.
So, the real answer is 2.5 < x, or x > 2.5.
Answer: (14.4 x 8)-4
Step-by-step explanation:
add 2.8 and 11.6 and multiply 8 your answer will be 115.2 but when you subtract it with the four you will get the same thing when you calculate the regular problem.I hope this help
