Answer:
Minimum 66 feet of molding that he needs.
Step-by-step explanation:
Given that a square ceiling has a diagonal of 23 ft.
If the sides of the square ceiling are 'a' feet, then applying Pythagoras Theorem we can write, a² + a² = 23²
⇒ 2a² = 23²
⇒ a = 16.2634 feet (Approximate)
Now, the perimeter of the square ceiling will be 4a = 65.05 feet.
If the cost of molding along the perimeter of the ceiling is in per foot, then a minimum of 66 feet of molding that he needs. (Answer)

Using distributive property,
f * n = fn
f * 5 = 5f
= fn + 5f
Answer:
n = -6 or n = 4.
Step-by-step explanation:
-3 | -8n – 8 | = -120
Divide both sides by -3:
| -8n – 8 | = 40
This gives us 2 equations because the expression in the absolute signs can be positive or negative:
-8n - 8 = 40
so -8n = 48
n = -6.
and
-8n - 8 = -40
-8n = -32
n = 4.
16 ounces is 1 pound which means that you can make 4 ounces, 8 times.
