QUADRANT 3 IS the right answer
Answer:
B
Step-by-step explanation:
Since the cones are similar then the ratio of corresponding sides are equal, that is
= 
( h is the height of the smaller cone )
Cross- multiply
18h = 540 ( divide both sides by 18 )
h = 30 cm → B

1. Solve inside bracket first
7x^2+4x-26+7x^2+3x-15
= (14x^2+7x-41) Answer
2. 5x(6x^2+3x+7)-1(6x^2+3x+7)
= 30x^3+15x^2+35x-6x^2-3x-7
= (30x^3+9x^2+32x-7) Answer
Answer:
19°
Step-by-step explanation:
Set up the equation (triangles add up to 180 degrees)(Right angles are 90 degrees).
39 + 90 + 2x + 13 = 180
142 + 2x = 180
2x = 38
x = 19
