Which statement best explains why the value of this expression is equal to −812y? 414x − 812y − 414x
GarryVolchara [31]
For this case we have the following expression:
 414x - 812y - 414x
 Rewriting we have:
 414x - 414x - 812y
 We group similar terms:
 (414x - 414x) - 812y
 Adding we have:
 0 - 812y
 - 812y
 Answer:

the bottom of a 22-foot ladder must be placed 7 feet from a wall. to the nearest tenth of a foot, how far above the ground does
Kitty [74]
The ladder, the wall and the floor form together a triangle rectangle, where the ladder is the hypotenuse of the triangle and the floor and wall are the cathetus. We know from Pythagoreas theorem that the square of the hypotenuse is equal to the sum of the two cathetus squared added, so we can write an equation with the data we have:
hyp^2 = cath1^2 + cath2^2
<span>hyp^2 = wall^2 + floor^2
</span>so we have the hypotenuse value, the floor value and the unknown is the wall height:
(22)^2 = wall^2 + (7)^2
484 = wall^2 + 49
wall^2 = 484 - 49 = 435
wall = √435
wall = 20.9
therefore the ladder touches the wall 20.9 feet above the ground
