Step-by-step explanation:
4-17x^2+16=0 s
Calculate multiply
20-17x^2=0
Reoder the term
-17x^2+20=0
Calculate the discriminat
D=0^2-4x(-17)x20
Simplify
D=1360
The quadric equation has 2 real solutions
So your Solution is :
2 real solutions
400 square feet because 10*40 is 400
Hey there! I'm happy to help!
The percent in the problem is 60% (as it has a percent time).
The base is the number we start with, so it is 485.
The amount is the percent of the base. As a decimal, 60% is 0.6. So, we just multiply this by 485.
0.6×485=291
Therefore, the amount is 291.
AMOUNT: 291
BASE: 485
PERCENT: 60%
Have a wonderful day! :D
