Answer:
Step-by-step explanation:
Here are the steps required to solve a quadratic using the quadratic formula:
Example 1 – Solve: x²-8x+14=0
Step 1: Identify a, b, and c and plug them into the quadratic formula. In this case a = 1, b = –8, and c = 14.
Step 2: Use the order of operations to simplify the quadratic formula.
Step 3: Simplify the radical, if you can. In this case you can simply the radical into:
Step 4: Reduce the problem, if you can. In this case you can reduce the entire problem by 2.
Step 1. Subtract 4m from both sides
d - 4m = 7n
Step 2. Divide both sides by 7
d - 4m/7 = n
Step 3. Switch sides
n = d - 4m/7
Answer:
x=< - 29/15 or x > 31/15
Step-by-step explanation:
Answer:
about 66%
Step-by-step explanation:
I tested this with the number 50.
50 x 50% = 25
25 x 300% = 75
50 / 75 = 2 / 3 = 66%
To prove:
75 x 66% ≈ 50
