Answer:
The expression represents JL is<u> 3x - 2</u>.
Step-by-step explanation:
Given:
JM = 5x – 8 and LM = 2x – 6.
Now, to find expression represents JL.
JM = JL + LM
<em>Subtracting both sides by LM we get:</em>
JM - LM = JL.
JL = JM - LM
Now, putting the expression to get JL:
Therefore, the expression represents JL is 3x - 2.
let the two numbers be x and y
From the first sentence,
xy=24
x+y=10
Then make y in equation 2 the subject of the formular and substitute in equation 1
x+y=10
y=10-x
substituting in equation 2
x(10-x)=24
open the bracket
10x-x^2=24
=-x^2+10x=24
Transfer the constant to the left hand side
=-x^2+10x-24=0
Then factorise completely
