Aladder is leaning against a building so that the distance from the ground to the top of the ladder is 1 foot less than the length of the ladder. find the length of the ladder if the distance from the vottom of the ladder to the building is 3 feet.

5

Step-by-step explanation:

Whenever there are problems that have ladders leaning on a buildings, you have to know that is makes a right triangle.

3^2 + (x-1)^2 = x^2

(x-1)(x-1) = x^2 - 2x + 1

9 + x^2 -2x +1 = x^2

-x^2                    -x^2

-2x +10 = 0

-10           -10

-2x=-10

-2x/2   -10/2

x=5 (the length of the ladder)

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
