Answer:
L = 5
Step-by-step explanation:
use Pythagorean Theorem:
L² + (5)² = (10
)²
L² + 25(2) = 100(3)
L² + 50 = 300
L² = 250
L = =
·
= 5
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
