Answer:
Step-by-step explanation:
The even number of minus signs means the product will be positive. A factor of 3 can be removed to simplify the product. As usual, the numerator of the product is the product of numerators, and the denominator of the product is the product of denominators.
The answer to the expression is 0.
In this expression, we have two terms that are identical: .
When we multiply a negative number by another negative number, the result is positive.
So, both of these terms become positive, and since they are identical, when we subtract one from the other, we get zero.
Now, let's provide a more detailed explanation.
When we multiply , we first multiply the numerators to get 9 and the denominators to get 42.
So, .
Now, we can simplify by dividing both the numerator and denominator by their greatest common divisor, which is 3.
So, simplifies to .
Therefore, the expression becomes , and when we subtract these two identical fractions, the result is indeed 0.

It is actually fourteen...you didvide 336 by 12 and since that slant is a triangle based shape you divide that by the quotient of 336\12, which is 14. Sorry if it’s a little confusing
Answer:
Volume of the portion = 1.6 cubic inches
Step-by-step explanation:
Since, wooden dowel is in the shape of a cylinder,
Formula to be used to find the volume of the part Anna has cut from the dowel will be,
Volume = πr²h
Where r = radius of the cylinder or part of the wooden dowel
h = length of the portion
By substituting the values in the formula,
Volume = π(0.5)²(2)
= 0.5π
= 1.57 in³ ≈ 1.6 cubic inch
Therefore, volume of the portion will be 1.6 in³.
