4: B
5: B
6: H (12)
8: C (3,-6)
7: 120
Step-by-step explanation:
6.
6x-6=3x+30
3x=36
x=12
7. 7x-6=5x+30
2x=36
x=18
5 x 18 = 90 +30 = 120
Answer:
Step-by-step explanation:
the diameter of this circle is 7.4 km
the radius of this circle is 7.4 km/2=3.7 km
second choice
Step-by-step explanation:
A = (1/2)bh ---> h = 2A/b = 2(12 cm^2)/(5 cm) = 4.80 cm
---> x^2 = h^2 + (b/2)^2
= (4.8 cm)^2 + (2.5)^2
= 23.04 cm^2 + 6.25 cm^2
or x = 5.41 cm
Therefore, the perimeter P is
P = 2x + b = 2(5.41 cm) + 5 cm = 15.8 cm
Answer:
(- 5, 2 )
Step-by-step explanation:
Under a reflection in the line y = x
a point (x, y ) → (y, x ), thus
(2, - 5 ) → (- 5, 2 )
