What are the x-intercepts of the quadratic function?

f(x)=x^2+2x−24

enter your answers in the boxes.

and

x= -6  and x= 4

Step-by-step explanation:

WE need to find x intercepts for the given quadratic function

To find x intercept we set f(x)=0 and solve for x

To solve for x we need to factor x^2 +2x-24

We need to find out two factors whose product is -24 and sum is 2

6 times -4= -24  and 6-4= 2

Break the middle term 2x using factors 6x-4x

0=(x+6)(x-4)

now we set each factor =0 and solve for x

x+6 =0 , so x=-6

x-4=0 so x= 4

x= -6  and x= 4

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
