Let the solutions be a and b.
a = -2; b = -10
a + b = -2 + (-10) = -12
ab = (-2)(-10) = 20
(x - a)(x - b) = 0
(x - (-2))(x - (-10)) = 0
(x + 2)(x + 10) = 0
x^2 + 10x + 2x + 20 = 0
x^2 + 12x + 20 = 0
-h = 12
h = -12
4k = 20
k = 5
Answer:
50 degrees.
Step-by-step explanation:
Angle FGE = 
because angles on a straight line add up to 180 degrees.
Angle EFG = 
(Angles in a triangle add up to 180)
Add 20 to both sides:
Subtract 6x from both sides:
Angle 
Answer:
A rational number is a number that can be represented a/b where a and b are integers and b is not equal to 0.

Answer: y = x + 4
Step-by-step explanation:
Since the total number of gasoline is given to be "y", with an initial quantity of filled gasoline to be "4" and the quantity of unfilled gasoline to be "x".
Therefore, the summation of the filled and unfilled quantity of gasoline will be "x + 4" which is equal to the total capacity of the tank "y".
Answer:
38,660
Step-by-step explanation:
54 thousands 6 hundreds 12 tens – 15 thousands 8 hundreds 26 tens
54 thousands = 54000
6 hundreds = 600
12 ten = 12*10 = 120
54 thousands 6 hundreds 12 tens = 54000+600+120 = 54720
15 thousands = 15000
8 hundreds = 800
26 tens = 26*10 = 260
15 thousands 8 hundreds 26 tens = 15000+800+260 = 16060
Thus,
54 thousands 6 hundreds 12 tens – 15 thousands 8 hundreds 26 tens
= 54720- 16060 = 38,660 (Answer)
