The area of the parallelogram is...
![5x^2+2x-1=0](https://tex.z-dn.net/?f=5x%5E2%2B2x-1%3D0)
Delta equation is:
![\Delta =\frac{-b\pm\sqrt(b^2-4ac)}{2a}](https://tex.z-dn.net/?f=%5CDelta%20%3D%5Cfrac%7B-b%5Cpm%5Csqrt%28b%5E2-4ac%29%7D%7B2a%7D)
but we are interested in
![b^2-4ac](https://tex.z-dn.net/?f=b%5E2-4ac)
because it determines the discriminant
![5^2-4*2*(-1)=25+8=33](https://tex.z-dn.net/?f=5%5E2-4%2A2%2A%28-1%29%3D25%2B8%3D33)
![33>0](https://tex.z-dn.net/?f=33%3E0)
which means that discriminant is positive :)
To answer this question we will have to keep the following two points in mind:
#1. The <u>sum</u> of a number with another number means to <u>add </u>the given two numbers.
#2.<u> Twice</u> means to <u>multiply by 2.</u> In other words it means to double.
Therefore, "twice the sum" would mean to multiply the sum by 2.
Now, in our question we will have, "the sum of y and 9 would be:
and twice this sum would be: ![2(y+9)](https://tex.z-dn.net/?f=%202%28y%2B9%29%20)
Thus, "twice the sum of y and 9" is: ![2(y+9)](https://tex.z-dn.net/?f=%202%28y%2B9%29%20)
Answer:
47.6
Step-by-step explanation:
always change "is" to =
and always change "of" to * (multiplication)
percent means Per Cent or Per 100 , so to eliminate the % sign, multiply the answer by 100
60=____% * 126
60=X(126)
divide both sides by 126
.476=X
.476 (100)
47.6
