Selection B is appropriate.
_____
The signs of the coefficients tell you the binomial factors must have both signs positive (selections B and C only). Selection B produces an x-term that is 15x+15x=30x (as we want); selection C produces an x-term that is 45x+5x=50x (not what we want).
Answer:
0.75487
Step-by-step explanation:
Answer:
Choice B: A triangle
Choice C : A shape with two edges, one straight and one curved
Step-by-step explanation:
When a cone is cut by a plane that runs exactly through its vertex, and perpendicular to its base, the shape that is obtained is an isosceles triangle, when the section is viewed.
When a cone is cut through a plane that runs perpendicularly to its base, but not through its vertex, we can get two different shapes which have parabolas or hyperbolas as their curved edge, and a straight edge which is formed from the base of the cone
Answer:
a). x = 9
b). m∠ABC = 27°
c). m∠CBD = 153°
Step-by-step explanation:
1). Property of linear pair of angles states, "sum of linear pair of angles is 180°"
3x + (15x + 18) = 180°
18x + 18 = 180
18x = 180 - 18
18x = 162
x = 9
2). m∠ABC = 3x°
= 3×9
= 27°
3). m∠CBD = (15x + 18)°
= (15×9 + 18)°
= (135 + 18)°
= 153°
