a ladder, 24m long, leans against a vertical wall and touches it 18m above the ground. How far is the foot of th ladder from the wall?​

15.87 m

Step-by-step explanation:

Length of ladder = hypotenus = 24 m

Height, opposite = 18m

Foot of ladder from the wall = x

Using Pythagoras rule :

Hypotenus² = opposite² + Adjacent²

x² = hypotenus² - opposite²

x² = 24² - 18²

x² = 576 - 324

x² = 252

x = √252

x = 15.87 m

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.
