Answer: x = 1.32 and x= 0.076
Step-by-step explanation:
4x(5x-2) = 20x-2
20x^2-8x = 20x-2
20x^2-8x-20x+2=0
20x^2-28x+2=0
Using quadratic equation
x = (-b +or- √(b^2-4ac))/2a
a =20, b=28, c= 2
Substitute into the equation
x= (7+√39)/10. = 1.32
x = (7-√39)/10 = 0.076

Step-by-step explanation:
<u>Step 1: Add the numbers: 9.5 +6.2 = 15.7</u>


<u>Step 2: Subtract the numbers: 15.7 - 12.25 = 3.45</u>

<u>Step 3: Multiply the numbers: 8.6 × 3.45 = 29.67</u>

- To solve this equation, the first step is to add the numbers 9.5 + 6.2 into the equation and it will lead to 15.7 as the number for step one.
- To solve this equation, the second step is to subtract the numbers 15.7 - 12.25 into the equation and it will lead to 3.45 as the answer.
- To solve this equation, the third step is to multiply the numbers 8.6 x 3.45 into the equation and it will lead 29.67 as the final answer for the whole equation.

9, 2, -5... so is going down by 7 each time, meaning the "common difference" is -7.
