Y = 18 x² + m x + 2
Exactly one x - intercept is for:
D = m² - 4 · 18 · 2 = 0
m² - 144 = 0
m² = 144
Answer:
m = -12 or m = 12
Answer:
Simple!
Step-by-step explanation:
Multiply 5 into each term into the parenthesis.
5-`10g + 20h
Answer:
15 feets, 11.25 inches
Step-by-step explanation:
Given that:
Scale = 1 : 48
Thus means that the model is 1/48 the actual size of the jet
Length of fighter jet = 63feets, 9 inches
Converting the entire length to inches
1 feet = 12 inches
63 feets = (12 * 63) = 756
Lenght of jet = (756 + 9) = 765 inches
1/48 * 765 = 15.9375 ; 15 feets, 11.25 inches
Hence, length of model = 15 feets, 11.25 inches
Answer:
$67.25
Step-by-step explanation:
52.60 x 8% = 52.60 x 0.08 = 4.21
52.60 x 20% = 52.60 x 0.20 = 10.44
52.60 + 4.21 + 10.44 = 67.25
2x^2 + 11x + 9
You can foil it to get the correct answer, (FOIL = First, Outter, Inner, Last)
