For the answer to the question above, I'll show my solution on how you can solve your problem.
AC² + BC² = AB²
5² + 12² = AB² 
25 + 144 = AB² 
169 = AB² 
13 = AB 

Triangle ABC is proportional to triangle ADB. 

AC = AB 
AB AD 

5 = 13 
13 AD 

5AD = 169 

AD = 169/5 

AD = 33.8 

AD = AC + CD 

33.8 = 5 + CD
So the answer is

CD = 28.8

Two positive integers have a sum of 15 and a product of 36. What are the integers?

joja [24]

Answer:

12 and 3

Explanation:

Let the integers be x and y

Their sum:

x + y = 15

rewrite

x = 15 - y

Their product:

(x)(y) = 36

rewrite

x = 36/y

Solving simultaneously:

36/y = 15 - y

36 = 15y - y²

y² - 15y + 36 = 0

(y - 12)(y - 3) = 0

y = 12, 3

X values:

when x = 12, y = 3

when x = 3, y = 12

The integers are 12 and 3

Step-by-step explanation:

Marcus lays a slab of concrete in 3 hours. Tony lays the same size slab in 2 hours. The number of hours used by both men will be:

1/3x + 1/2x = 1

2x + 3x = 6

5x = 6

x = 6/5 = 1.2 hours.

The cost of labor will be:

= 1.2 hours × $48

= $57.60
