Answer:
Global warming is a huge problem
Step-by-step explanation: If the ice caps melts, that means that there is more water in the ocean, the more water in the ocean, the less land there is to live on.
Answer: -2.8
Step-by-step explanation:
3t-(8/5) * 4-t < -7
(15t-8)/5 * 4-t < -7
((15t-8)(4-t))/5 < -7
(15t^2)-28t-32< -7
(15t^2)-28t-32-7< 0
(15t^2)-28t-39< 0
Using the quadratic/almighty formula
t= (-b +- ((b^2)-4ac)^(1/2)/2a)
a=15, b=-28, c=-39
t= (-(28) +- (((-28)^2)-4(15)(-39))^(1/2))/2(15))
t= -2.8 or t= 0.9
Since
t<0, then t= -2.8
Answer:
--9x^3+12x^2-x-2
Step-by-step explanation:
(2-3x)(3x^2-2x-1)
6x^2-4x-2-9x^3+6x^2+3x
-9x^3+6x^2+6x^2+3x-4x-2
-9x^3+12x^2-x-2
Answer:
- angle: 120°
- its supplement: 60°
Step-by-step explanation:
Let "a" represent the measure of the angle. Then 180-a is the measure of its supplement. Your equation can be ...
a = 2(180-a) . . . an equation
a = 360 -2a . . . . eliminate parentheses
3a = 360 . . . . . . add 2a
a = 120 . . . . . . . . divide by 3 to find "an angle"
180-a = 60 . . . . . find "its supplement"
The measure of the angle is 120°, of its supplement, 60°.
