-7 and 2 or 8 and 17

Step-by-step explanation:

If we let the numbers be and x+9 , the equation to solve this problem will be as follows:

x(x+9)=5(x+x+9)+11

Solving the equation for , we get:

x(x+9)=5(x+x+9)+11

x(x+9)=5(2x+9)+11 (Combine like terms)

$x^{2} +9x=10x+45+11$ (Use the Distributive Property of Multiplication to multiply expressions)

$x^{2} +9x=10x+56$ (Combine like terms)

$x^{2} -x-56=0$ (Subtract 10x and from both sides of the equation)

$x^{2} -8x+7x-56$ (Split )

x(x-8)+7(x-8)=0 (Factor by taking a common term out)

(x-8)(x+7)=0 (Factor by taking a common term out)

x-8=0 or x+7=0 (Use the Zero Product Property)

x=8 or x=-7

Therefore, the first number could be either -7 or 8, and the second number could be -7 + 9 = 2 or 8 + 9 = 17, respectively. Hope this helps!

"it's not the heat, it's the humidity". that's a partly valid phrase you may have heard in the summer, but it's actually both. the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature. this has important considerations for the human body's comfort. when the body gets too hot, it begins to perspire or sweat to cool itself off. if the perspiration is not able to evaporate, the body cannot regulate its temperature. evaporation is a cooling process. when perspiration is evaporated off the body, it effectively reduces the body's temperature. when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases. in other words, the human body feels warmer in humid conditions. the opposite is true when the relative humidity decreases because the rate of perspiration increases. the body actually feels cooler in arid conditions. there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
