The real zeros are -8 and -9
Answer:
The answer is b, c, d and e
Cirrus clouds form at a height of more than 6000 meters above the earth. This means the inequality should represent the height more than 6000. The correct inequality for this case will be:

This inequality shows that h which is height where Cirrus clouds are formed is greater than 6000m.
Answer:
x-3 _< 14
Step-by-step explanation:
Answer:
angle C =160 degree
Step-by-step explanation:
since the given triangle is an isosceles triangle their base angles must be equal. So,
x - 10 =x/2
2(x - 10) =x
2x - 20 = x
2x - x = 20
x = 20
for angle B
x - 10
20 - 10
10 degree
for angle A
x/2
20/2
10
For angle c
angle A + angle B + angle C =180 degree (sum of interior angle of a triangle)
10 + 10 + angle C =180
20 + angle C =180
angle C =180 - 20
angle C =160 degree
