Answer:
X<-11/2
Step-by-step explanation:
Hope I helped:)
It should be 12 ft away from the wall. Not 4 ft. You do not just subtract the difference because as you pull it away from the wall, the ladder is mostly moving horizontally with only a small vertical change.
You can use Pythagorean Theorem to find the answer. Think of the ladder as the hypotenuse of a right triangle with the wall and the ground as the legs.
a^2 + b^2 = c^2
16^2 + b^2 = 20^2
b^2 = 20^2 - 16^2
b^2 = 144
b = 12 ft
Answer:
The coordinates of the end point B are (14 , 8)
Step-by-step explanation:
let B(x , y)
M midpoint of A and B
⇔ 8=(x+2)/2 and 11=(y+14)/2
⇔ 16=x+2 and 22=y+14
⇔ x=14 and y=8
Answer:
A.-2x2+-1
Step-by-step explanation:
(-7x+5)-(2x2-8x+6)
-7x+5-2x2+8x-6 then collect like terms
-2x2-7x+8x+5-6
-2x2-x+1
