X^2+x-12=0 factors out into (x+4)(x-3) so the answer is: x=-4, x=3
Hey!
-------------------------------------------------
This just shows to substitute all of x with -1.
g(-1) = 3(-1) - 5
g(-1) = -3 - 5
g(-1) = -8
-------------------------------------------------
Hence, the answer is -8!

Hope This Helped! Good Luck!
The second part would be $700. I'm not sure how I would solve the first part. You should click the hint button.<span />
Answer:
D. The plane needs to be about 27 meters higher to clear the tower.
Step-by-step explanation:
In this scenario a triangle is being formed. The base the plane's takeoff point to the tower base which is 42 meters (x).
The hypothenus is the distance travelled by the plane which is 83 meters (h)
The height of the tower is 98 Meters
We want to calculate the height of our triangle (y) so we can guage if the plane scaled the tower.
According to Pythagorean theorem
(x^2) + (y^2) = h^2
y = √ (h^2) - (x^2)
y = √ (83^2) - (42^2)
y= √(6889 - 1764)
y= 71.59 Meters
The height from the plane's position to the top of the tower will be
Height difference = 98 - 71.59 = 26.41 Meters
So the plane should go about 27 Meters higher to clear the tower
