Answer:
0.25 cents
Step-by-step explanation:
Yes they are equivalent. For the first one you reduce the second equation by 2. For the second pair you reduce the second equation by -3.
First, solve the parenthesis
Remember to follow PEMDAS, and the left-> right rule
12/3 = 4
4 x 2 = 8
8 + 3 = 11
11 - 7 = 4
Square the remaining number
4² = 4 x 4 = 16
16 is your answer
hope this helps
Answer:
x = 3 ± √5
Step-by-step explanation:
The expression (x - 3)² = 5 doesn't need completing the square to solve (this is the step after you finish completing the square):
Step 1: Square root both sides
x - 3 = ±√5
Step 2: Add 3 to both sides
x = 3 ± √5 = 0.76392, 5.23607
This can be written as...
(1/2)/(1/4) = h/1
Then you solve all of the fractions by multiplying them by 4 to make them intergers;
4(1/2)/4(1/4) = 2/1 = h/1
This means h is equal to 2.
Hope this helps! :)
