X square - 5 x - 24 = 0 Answer pls​

Mathematics
1 answer:
Goryan [66]3 years ago
3 0

Answer:

x = -3 and x = 8

Step-by-step explanation:

x^2 - 5x - 24 = 0

First you factor the equation:

(x - 8)(x + 3) = 0

Then set each factor equal to zero.

x - 8 = 0

x = 8

and

x + 3 = 0

x = -3

So you have two possible answers for x -- -3 and 8

a pole that is 3.3 M tall casts a shadow that is 1.22 M long at the same time a nearby Tower cast a shadow that is 50.75 M long
jenyasd209 [6]
Since there is no distance between the pole and the base of the tower, we can assume that the pole is at the base of the tower. 
We can create a right triangles between the pole and its shadow and between the tower and its shadow as shown in the figure. Let x be the height of the tower. Since our triangles are similar the ratio between its sides is going to be proportional, so we can establish a proportion to find x:
\frac{x}{3.3} = \frac{50.75}{1.22}
x= \frac{(50.75)(3.3)}{1.22}
x=137.27

We can conclude that the tower is 137.27 meters tall.
