Answer:
B and D
Step-by-step explanation:
The quadratic formula is 
. Here a=20, b=-26, and c=8.
Substitute and you'll have:
This means the solutions are 26 - 6/ 40 and 26 + 6/ 40.
It simplifies to 1/2 and 4/5.
Hey there!
PEMDAS simply means (the OVERALL question answer)
• Parentheses
• Exponents
• Multiplication
• Division
• Addition
• Subtraction
Here’s an example
24 - 4^2 + 2 * 4
= 24 - 16 + 2 * 4
= 24 - 16 + 8
= 8 + 8
= 16
Thus, the answer for that equation is: 16
Often people remember PEMDAS by saying. (So, I’d advise you think of it like that way as well!)

2 1/2 = 2.5
12 1/2 = 12.5
This means you can calculate how may times it goes in by dividing it and rounding the number down:
12.5 / 2.5 = 5
*5 can not be rounded down so it stays the same
This means that 2 1/2 goes into 12 1/2 5 times. Hope this helps! :)
