Answer:
x = -3, -6.
Step-by-step explanation:
3x2 + 27x + 54 = 0
Divide through by 3:
x^2 + 9x + 18 = 0
(x + 3)(x + 6) = 0
x = -3, -6.
The a and b determine how big or small the shape of the conic section is.
<span>For the different conic sections given through the equations </span>
<span>Circle: x^2/a^2 + y^2/a^2=1 </span>
<span>Ellipse: x^2/b^2+y^2/a^2 = 1 </span>
<span>Hyperbola: x^2/a^2 - y^2/b^2 = 1 </span>
<span>When trying to isolate cos and sin from those equations to get cos^2t + sin^2 t = 1 you can determine the conic section when substituting cos t = x/a and sint = y/b into cos^2t+sin^2t square it and then refer to the conic section equations to determine the conic section. x defines the major axis and y is the minor axis. a and b provide the coordinate pairs</span>
10 x 7 = ?(70) 25 x 7 = ?(175) 175 + 70 = 245
Pythagorean theorem
25^2 = x^2 + x^2
so 625 = 2x^2
312.5 = x^2
17.68 = x
17.68 feet is your answer
The answer is D because that is the right answer 27
