Since -6 +6 can be rearranged to 6-6 using the communicative property, we get 6-6 =0 . In addition, -120+(-6) is essentially having -120+ 1*(-6), and 1 times a number is simply that number, so we have -120-6=-126

If you place a 26-foot ladder against the top of a 10-foot building, how many feet will the bottom of the ladder be from the bot

True [87]

Answer:

24 foot

Step-by-step explanation:

We are given that

Length of ladder=26 foot

Height of building=10 foot

We have to find the distance between the bottom of ladder and the bottom of building.

Pythagorus theorem:

$(Hypotenuse)^2=(Base)^2+(Perpendicular\;side)^2$

We have hypotenuse =AC=26 foot

Perpendicular side =AB=10 foot

Base=BC

Substitute the values in the given formula

$(26)^2=(10)^2+(BC)^2$

$676=100+(BC)^2$

$(BC)^2=676-100=576$

$BC=\sqrt{576}=24$ (Take positive because length is always positive)

BC=24 foot

Hence, the bottom of the ladder will be 24 foot from the bottom of the building.
