Answer:
Step-by-step explanation:
The given quadratic trinomial is 
Where a=6, b=-13 and c=-5
The factors of -30 that add up to -13 are -15,2
We split the middle term to get:
Factor by grouping:
These completely factors to:
Answer:Well, one of those rules is called the subtraction property of inequality, and it basically says that if you minus a number from one side of an inequality, you have to minus that same number from the other side of the inequality as well. -virtualnerd.com

Answer:
2x + 3y = -13
Step-by-step explanation:
We can first find the equation of the line in point-slope form. The slope of the line is given by 
, which is (-5-(-3))/(1-(-2)), or -2/3. The equation for a line in point-slope form is 
where 
is the slope and 
is a point on the line -- in this case, we may use (1, -5). Therefore, the equation for the line is y + 5 = -2/3 (x-1).
The question asks for the equation of the line in standard form -- which is 
. We can get this by simplifying the equation above to get
.
We have to find 2 areas and to subtract A2 from A1:
A1 = ( r² · π · 45° ) / 360° = ( 6² · 3.14 · 45° ) / 360° = 14.13 ft²
A2 = ( 3² · π · 45° ) / 360° = 3.53 ft²
A ( BCIH ) = 14.13 - 3.53 = 10.6 ft² ≈ 11 ft²
Answer: The area of the glass in the region BCIH is 11 ft² ( rounded to the nearest square foot ).
