Answer:
about 22.2 feet
Step-by-step explanation:
The wire can run diagonally across the floor and, from the intersection with the wall, diagonally up the wall. The total length is computed per the hint to be ...
d = √(18^2 +13^2) = √493 ≈ 22.20 . . . . feet
___
If the wire were to go up the short wall, its length would be ...
d = √(11^2 +20^2) = √521 ≈ 22.83 . . . . feet
_____

The red represents the floor; the green represents the long wall.
Answer:
X = 4√3
Step-by-step explanation:
Using tangent-secant theorem
So,
X² = (4)(4+8)
X² = (4)(12)
X² = (48)
Taking sqrt on both sides
X = 4√3
Answer:
x = 30
Step-by-step explanation:
The perimeter is the sum of all of the sides of a shape. Therefore, because the sum is equivalent to 104 inches and we are given the lengths of all three sides, we can add the three sides together and set them equal to 104 in order to solve for x.
(x + 3) + (x + 4) + (x + 7) = 104 Drop the parentheses.
x + 3 + x + 4 + x + 7 = 104 Combine like terms (variables first!).
3x + 3 + 4 + 7 = 104 Now, combine constant terms.
3x + 14 = 104 Subtract 14 from both sides.
3x = 90 Divide by 3 on both sides of the equation.
x = 30
Answer:
we need to buy 8 packs of hot dogs and 10 packs of hot dog buns
Step-by-step explanation:
To answer the question above, simplify both sides of the equation. This gives,
8x - 3 = 8x + 14
Next, cancel the term 8x because it appears on both sides of the equation giving,
-3 = 14
That is NOT true. Therefore, the answer is the equation is NEVER TRUE.
