x= 8 , -3
<h3>What is Quadratic Equation?</h3>
Given:
x² - 5x -24 =0
x² - 8x + 3x -24=0
x(x-8) + 3(x- 8)=0
(x-8)(x+3)=0
x= 8 , -3

Ex step sister 68/09(78+09)=
Answer:
Step-by-step explanation:
Ax+By=C (remember this formula)
-2/9x+2=y (switched sides to make it easier)
-2x/9+2-y=0 ( put y on the other side)
-2x/9-y=-2 ( put 2 on the other side)
So a must be positive so multiply by -1
2x/9+y=2
answer
2x+9y=18 (LCM)
Step-by-step explanation:
To find perimeter, you need to add all the sides of the shape.
The area of a traingle is 1/2 bh.
You must find the "b" in order to find the perimeter.
Example:
A triangle has an area of 18 cm^2.
Therefore, the triangle has a 6 cm base and 6 cm height.
Then multiply the base by three to get 18 cm. That is your perimeter.
