<u>Answer:</u>

<u>Explanation:</u>
We are given product of two consecutive odd integers is equal to 72.
Let one integer be x , then since these are consecutive and odd so the other integer will be equal to x + 1.
Their product is equal to 72. So,
x * (x + 1) = 72
=> 
=>
is the required quadratic equation.
Answer:
Cada uno de ellos gana:
S/. 24
S/. 36
Step-by-step explanation:
Planteamiento:
a + b = 60
a = 12 + b
Desarrollo:
sustituyendo el valor de la segunda ecuación del planteamiento en la primer ecuación del planteamiento:
(12+b) + b = 60
2b + 12 = 60
2b = 60 - 12
2b = 48
b = 48/2
b = 24
de la segunda ecuación del planteamiento:
a = 12 + b
a = 12 + 24
a = 36
Check:
24 + 36 = 60
It takes the faster pump 12 minutes to fill the tank.
Since the faster truck can produce 60% more than the other truck. 60% of 20 minutes is 12.

Answer:
NK=12
Step-by-step explanation:
x^2 +9^2=15^2
x^2+81=225
subtract 81
x^2=144
x=12
