Step-by-step explanation:não falo inglês
Answer:The solutions are:x = -5
x = -6
Explanation:To get the solution, we can either use a graphical method or an algebraic method.
1- graphical method:The solution of the equation would be the values of the x-intercept.
Graphing the equation (check attached image), we would find that the solutions are: -6 and -5
2- algebraic method:The general formula of the quadratic equation is:
ax² + bx + c = 0
The given equation is:
x² + 11x + 30 = 0
By comparison:
a = 1
b = 11
c = 30
To get the roots, we will substitute in the quadratic formula (attached in the images)
Doing this, we will find that:
either x =

= -5
or x =

= -6
Hope this helps :)
Given:
AC = √(-2-3)² + (6-2)²
AC = √ -5² + 4²
AC = √ 25 + 16
AC = √41
AC = 6.40
I am assuming that the triangle is an equilateral triangle. This means that all sides are equal.
AC = AB = BC
Perimeter = 6.40 * 3 sides = 19.20
Answer:
20%
Explanation:
What we know:
- there are 25 cans in total
- 5 of them are root beer cans
Using this information, we can say that 5/25 cans are root beer cans. To find the percent, we change the fraction into a decimal and then multiply it by 100.
To change 5/25 into a decimal, we divide the numerator and denominator.
5/25=0.2
And we multiply the decimal by 100 to get the percent:
0.2*100=20
Therefore, 20% of Cam’s cans are root beer cans.
I hope this helps!
