In quadratic equations,
a + b = -B
ab = C
where a and b are the roots, B is the second term, and C is the constant.
Substituting,
a + b = -12
ab = 35
The values of a and b from the equation is -7 and -5. Thus, the lesser root is -7.
D is correct because it is a tenth and it becomes a hundredth
125 miles per hour is equal to 201.168 kilometers per hour.
If I were solving this equation, I would put x^2-20x+(100)=(10). Since this is in standard form, you could change this into vertex form by making the equation y=(x-10)^2 -10.
Answer:
The answer to your question is: B and D are correct
Step-by-step explanation:
Remember that the sum of the internal angles in a triangle equals 180°.
The sum of supplementary angles equals 180°
Then
(6x + 1) + (4x + 5) + [180 - (8x + 30)] = 180
6x + 1 + 4x + 5 + [180 - 8x - 30] = 180
10x + 6 + 150 - 8x = 180
2 x = 180 - 156
2x = 24
x = 24/2
x = 12
∠JKL = 4(12) + 5 = 48 + 5 = 53
∠KJL = 6(12) + 1 = 72 + 1 = 73
∠KLJ = 180 - 73 - 53 = 54
∠KLM = 126
